[Bug #18117] Fix Ractor race condition with GC rb_objspace_reachable_objects_from requires that the GC not be active. Since the Ractor barrier is not executed for incremental sweeping, Ractor may call rb_objspace_reachable_objects_from after sweeping has started to share objects. This causes a crash that looks like the following: ``` <internal:ractor>:627: [BUG] rb_objspace_reachable_objects_from() is not supported while during_gc == true ``` Co-authored-by: Vinicius Stock <vinicius.stock@shopify.com> --- bootstraptest/test_ractor.rb | 15 +++++++++++++++ ractor.c | 12 ++++++++++-- 2 files changed, 25 insertions(+), 2 deletions(-) |
