If you have time, can you try to find larger values changed by r59047 (RUBY_THREAD_MACHINE_STACK_SIZE and RUBY_FIBER_MACHINE_STACK_SIZE) which do not get stuck/segfault on PPC? Worst case is we define larger minimum values in vm_core.h for PPC. Best case is we find stack usage bloat on PPC and fix it :> ppc64le? I don't know much about PPC and did not know there is little-endian PPC. So it's PPC-specific and not BE-specific... *scratches head* Unsubscribe:
