Issue #20264 has been updated by byroot (Jean Boussier). The interesting parts from the upstream ticket: ``` Segmentation fault at 0x0067ffffb37006c0 ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [aarch64-linux] -- Control frame information ----------------------------------------------- c:0012 p:---- s:0068 E:002060 CFUNC :next c:0011 p:0005 s:0064 e:000063 BLOCK /usr/local/bundle/ruby/3.3.0/gems/pkg-config-1.5.6/lib/pkg-config.rb:439 c:0010 p:0018 s:0060 e:000059 METHOD <internal:kernel>:187 c:0009 p:0014 s:0055 e:000054 METHOD /usr/local/bundle/ruby/3.3.0/gems/pkg-config-1.5.6/lib/pkg-config.rb:438 c:0008 p:0035 s:0048 e:000047 METHOD /usr/local/bundle/ruby/3.3.0/gems/pkg-config-1.5.6/lib/pkg-config.rb:403 c:0007 p:0003 s:0039 e:000038 METHOD /usr/local/bundle/ruby/3.3.0/gems/pkg-config-1.5.6/lib/pkg-config.rb:297 c:0006 p:0007 s:0033 e:000032 METHOD /usr/local/bundle/ruby/3.3.0/gems/pkg-config-1.5.6/lib/pkg-config.rb:603 c:0005 p:0108 s:0028 e:000025 METHOD extconf.rb:111 c:0004 p:0018 s:0016 e:000015 METHOD extconf.rb:53 [FINISH] c:0003 p:---- s:0012 e:000011 CFUNC :new c:0002 p:0067 s:0008 E:000f60 EVAL extconf.rb:449 [FINISH] c:0001 p:0000 s:0003 E:000520 DUMMY [FINISH] ``` Unfortunately, no C-level backtrace included. So it's crashing in `Enumerator#next` on this line https://github.com/ruby-gnome/pkg-config/blob/eff47c9f57f8411b5e3c535cae0d8e... ```ruby def normalize_cflags(cflags) normalized_cflags = [] enumerator = cflags.to_enum begin loop do cflag = enumerator.next # CRASH! normalized_cflags << cflag case cflag when "-I" normalized_cflags << enumerator.next end end rescue StopIteration end normalized_cflags end ``` I haven't tried to repro yet. ---------------------------------------- Bug #20264: Segfault installing RMagick on M1 Mac https://bugs.ruby-lang.org/issues/20264#change-106711 * Author: andy@andyjeffries.co.uk (Andy Jeffries) * Status: Open * Priority: Normal * ruby -v: 3.3 * Backport: 3.0: UNKNOWN, 3.1: UNKNOWN, 3.2: UNKNOWN, 3.3: UNKNOWN ---------------------------------------- I raised a bug at RMagick, they said to go to pkg-config. I raised a bug there, and they said to raise it here. Hopefully this is the right place... https://github.com/ruby-gnome/pkg-config/issues/24 Simplest reproduction steps (although a full backtrace of a Rails app trying to do it is at the link above): ``` $ docker run -it --platform=linux/arm64 registry.docker.com/library/ruby:3.3-slim bash root@163711a82570:/# apt-get update root@163711a82570:/# apt-get install --no-install-recommends -y build-essential pkg-config libmagickwand-dev root@163711a82570:/# gem install rmagick ``` -- https://bugs.ruby-lang.org/
