Issue #19358 has been updated by eightbitraptor (Matthew Valentine-House). Can confirm that applying the patch from https://bugs.ruby-lang.org/issues/19284 to the 3.1.3 branch fixes the issue for me. I think this should be marked for Backport What do you think @peterzhu2118 ---------------------------------------- Bug #19358: Segfault when setting RUBY_GC_HEAP_INIT_SLOTS to a low value https://bugs.ruby-lang.org/issues/19358#change-101371 * Author: xfalcox (Rafael Silva) * Status: Open * Priority: Normal * ruby -v: ruby 3.1.3p185 (2022-11-24 revision 1a6b16756e) [x86_64-linux] *
