[ruby-core:125794] [Ruby Bug#22104] Segfault in PRISM while Bootsnap compiles aws-sdk client_api.rb

19 Jun 2026

      Issue #22104 has been updated by Morred (Laura Eck).

Thank you for your patience.

I disabled the GC and wasn't able to get it to segfault. However, I think that's inconclusive because it's an intermittent error and with the GC on I can't reliably reproduce it either.

Here are the details about the threads:

Bug #22104: Segfault in PRISM while Bootsnap compiles aws-sdk client_api.rb
https://bugs.ruby-lang.org/issues/22104#change-117713

* Author: Morred (Laura Eck)
* Status: Open
* ruby -v: 4.0.4
* Backport: 3.3: UNKNOWN, 3.4: UNKNOWN, 4.0: UNKNOWN
----------------------------------------
I'm seeing intermittent segmentation faults on aarch64-linux when Ruby compiles large auto-generated AWS SDK files, triggered through Bootsnap's ISeq compile cache.

Observed while compiling:

aws-sdk-dynamodb-*/lib/aws-sdk-dynamodb/client_api.rb
aws-sdk-rds-*/lib/aws-sdk-rds/client_api.rb

**Environment:**

ruby 4.0.4 (2026-05-12 revision b89eb1bcbf) +YJIT +PRISM [aarch64-linux]

I'm attaching two full backtraces including C level backtrace information:

**Backtrace 1:**

```
/usr/local/bundle/ruby/4.0.0/gems/aws-sdk-dynamodb-1.165.0/lib/aws-sdk-dynamodb/client_api.rb: [BUG] Segmentation fault at 0x0000aaab1cc9e000
