Issue #22104 has been updated by luke-gru (Luke Gruber). A large commit to prism landed on Mar 19 (78ab3a7ced8). It looks like some `RB_GC_GUARD`s were improperly placed in `pm_parse_string`, which *could* result in some weird behavior like we're seeing. I've got a [PR](https://github.com/ruby/ruby/pull/17292) for it, but it could very well be unrelated as well. Without a reproduction, it's impossible to know obviously. I'll merge it anyway and backport it to 4.0. ---------------------------------------- Bug #22104: Segfault in PRISM while Bootsnap compiles aws-sdk client_api.rb https://bugs.ruby-lang.org/issues/22104#change-117715 * 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.
