小さいコードでバグ再現できました
多分これでSEGVでると思います

a.call
}

* thread_pthread.c (ruby_init_stack): use stack info if possible.

* thread_pthread.c (ruby_init_stack): adjust stack size for offset of
  addr from the bottom.

* thread_pthread.c (get_stack): seems stack size does not include
  guard size on Mac OS X.

* gc.h (IS_STACK_DIR_UPPER): utility macro.

* thread_pthread.c (get_stack): Linux is the only OS which includes
  the size of guard page into the stack size.

* thread_pthread.c (ruby_init_stack): STACK_GROW_DIR_DETECTION is
  necessary on platforms with unknown stack direction.  [Bug #6761]
