Bug #21171
open
Segfault on large stack (RUBY_THREAD_VM_STACK_SIZE) on 3.4.2
Description
maybe related to #17583 ?
We are using Ruby with large RUBY_THREAD_VM_STACK_SIZE (as large as 128MB currently).
Ruby 3.4.2 (also happened on Ruby 3.4.0, 3.4.1) crashes if RUBY_THREAD_VM_STACK_SIZE is larger than 15958016 (= 15.21875MiB)
Tested on Docker with ruby:3.4.2-bookworm image (on Amazon Linux 2, aarch64), and ruby:3.y.z-bookwarm` for other versions as well.
