Thank you for this bug report. Could you run this script and paste the output? It will
help me to debug this issue.
```
require "objspace"

end
end
end
OBJ_COUNT = 500
GC.verify_compaction_references(expand_heap: true, toward: :empty)
ary = OBJ_COUNT.times.map { Foo.new }
ary.each(&:add_ivars)
GC.start
foo = Foo.new
foo.add_ivars
puts "--- BEFORE COMPACT"
puts GC.stat

I observe the following error:
Hey. I have been unable to replicate this test failure on both my development environment,
which is Fedora 37, or a toolbox container running Rawhide, both on x86_64. In addition to
the script output that @peterzhu2118 has requested - could you let us know what
architecture this is failing on for you, is it consistent or intermittent?
As an aside, this should be a test failure rather than raising a `NoMethodError`. I'll
look at that

It was x86_64. And I hit the issue for the first build run.
I did not have enough time to play with the issue, I have just reported the ticket once I
have encountered the issue. But I'll try to provide more feedback tomorrow.

New subject: [ruby-core:111384] [Ruby master Bug#19248] TestGCCompact#test_moving_objects_between_size_pools test failure
Issue #19248 has been updated by peterzhu2118 (Peter Zhu).
Thanks for running the script! From the output it looks like the read barrier is not being
triggered, so the objects aren't being moved back. It also looks like the objects are
being moved but just not upwards. I'm really not sure what's causing the objects
to not be moved upwards.
I tried running a Fedora Rawhide docker container (from
registry.fedoraproject.org/fedora:rawhide) on my x86_64 Ubuntu 22.04 machine, but I was
not able to replicate this bug. I'll try a VM next, but I've got a few other
things I need to before Ruby 3.2.0 release (which is in about 2 days), so I can't
promise that I'll be able to work on this before then. But I'll certainly get back
on this in the new year!

New subject: [ruby-core:111399] [Ruby master Bug#19248] TestGCCompact#test_moving_objects_between_size_pools test failure
Issue #19248 has been updated by vo.x (Vit Ondruch).
Just FTR, this is result on the official builder (will be garbage collected in several
days, sorry):
https://koji.fedoraproject.org/koji/taskinfo?taskID=95624219
You can check the build.log for each of the platforms. And it seems the test is passing on
i686/s390x while failing on x86_64/ppc64le/aarch64. If you can't reproduce in
container, can it be Kernel related?

It looks like your build system is patching files in Ruby? If so, could you provide these
files and/or look into potentially upstreaming it?
In particular, there's a file called `always-use-i386`. Is it forcing things to be
built for i386?

I have certainly tried at times. But let me try to build without them.
In particular, there's a file called
`always-use-i386`. Is it forcing things to be built for i386?
We carry this around for a while:
https://src.fedoraproject.org/rpms/ruby/blob/rawhide/f/ruby-2.1.0-always-us…
It should apply to just i386/i686 builds IMO. I have tried to get rid of it, but I am not
sure what effect it actually has 😬

Issue #19248 has been updated by vo.x (Vit Ondruch).
So far, it seems the key are the compiler flags. Going with default, the test case passes,
using Fedora flags, the test case fails. These are hopefully the relevant parts of the
log:

Issue #19248 has been updated by peterzhu2118 (Peter Zhu).
Thank you for checking the patches and testing different configurations. It looks like
you're using quite a lot of custom configuration flags, most of which I'm not too
familiar with. I'll look into this in the new year and debug the issue.

Issue #19248 has been updated by mtasaka (Mamoru Tasaka).
This seems also due to LTO, adding `%global _lto_cflags %{nil}` to ruby.spec, i.e.
removing `-flto=auto -ffat-lto-objects` from compilation flag seems to make this test
pass.

Issue #19248 has been updated by peterzhu2118 (Peter Zhu).
Thanks to @mtasaka and @vo.x for debugging this further! Using this information, I think
this is a bug in GCC. Here's what I did:
- I can confirm that I can reproduce this bug on Ubuntu 22.04 and GCC 11.3.0 with:
```
CFLAGS='-O2 -flto=auto -ffat-lto-objects -fexceptions -g -grecord-gcc-switches -pipe
-Wall -Werror=format-security -Wp,-D_FORTIFY_SOURCE=2 -Wp,-D_GLIBCXX_ASSERTIONS
-fstack-protector-strong -m64 -mtune=generic -fasynchronous-unwind-tables
-fstack-clash-protection -fcf-protection'
```
- I noticed during debugging the function
[`rb_shape_traverse_from_new_root`](https://github.com/ruby/ruby/blob/837ef8911c638c3e2bdb6af710de7c1fac7b5f90/shape.c#L448)
had seemingly impossible behaviour. I confirm that if I disable optimizations on that
function, then test passes as expected.
```c
#pragma GCC push_options
#pragma GCC optimize ("O0")
rb_shape_t *
rb_shape_traverse_from_new_root(rb_shape_t *initial_shape, rb_shape_t *dest_shape)
{
// ...
}
#pragma GCC pop_options
```
- I further isolated it down by setting `CFLAGS='-flto=auto'`, which causes Ruby
to segfault.
- Interestingly, disabling optimizations (`CFLAGS='-O0 -flto=auto'`) causes the
test to pass.
As such, I think there's an issue with `-flto` that causes bugs in Ruby.

Issue #19248 has been updated by alanwu (Alan Wu).
Looking at `rb_shape_traverse_from_new_root()`, it seems like it's triggering UB
in a way that also failed with LTO in the past. Maybe try this patch to confirm?

Issue #19248 has been updated by alanwu (Alan Wu).
@vo.x You might want to consider packaging with `-fno-strict-aliasing`.
I suspect the perf loss should be minimal if noticeable at all and it would
mitigate these type of strict aliasing violations, yielding an artifact more likely to be
correct.
Using LTO increases the exposure to strict aliasing violations. Since these bugs are
rather
arcane and time consuming to track down you might consider this to be a good compromise.

Issue #19248 has been updated by vo.x (Vit Ondruch).

@vo.x Do you need this backported to Ruby 3.2 or is it
ok to keep it only on the master branch (i.e. it will be part of Ruby 3.3)?
Unfortunately, I have no idea how likely is to hit this in real applications. I'd
leave the decision to you. For the moment, I have disabled the test case in Fedora, so the
only advantage from my POV would be to make the Fedora .spec file a bit cleaner, which is
never bad thing ;)
alanwu (Alan Wu) wrote in #note-21:
@vo.x You might want to consider packaging with
`-fno-strict-aliasing`.
Generally, I leave the decision about the compiler options to distribution. From that POV,
I don't think using `-fno-strict-aliasing` is an option. Of course if this was deemed
the right compiler option by Ruby upstream, that would be different thing.

I flagged it for backporting so it will be available on Ruby 3.2.1 :)
