Bug #17583
Updated by yoshiokatsuneo (Tsuneo Yoshioka) about 3 years ago
When I set large stack size like 100MB using RUBY_THREAD_VM_STACK_SIZE, I get the segmentation fault. The error looks happens when RUBY_THREAD_VM_STACK_SIZE is larger than around 17MB. How to reproduce: ``` ruby $ RUBY_THREAD_VM_STACK_SIZE=17000000 RUBY_THREAD_MACHINE_STACK_SIZE=1000000 ruby -e '' ``` Output: ``` # root@158c25395b8b:/# RUBY_THREAD_VM_STACK_SIZE=17000000 RUBY_THREAD_MACHINE_STACK_SIZE=1000000 ruby -e '' /usr/local/rbenv/versions/3.0.0/lib/ruby/3.0.0/x86_64-linux/enc/encdb.so: [BUG] Segmentation fault at 0x0000000000000048 0x0000000000000018 ruby
