The problem is that the function is defined *as static* in thread_pthread.c, but is used in thread.c. Not being an expert on threads, I thought that maybe `ubf_list_atfork` is a function that's available on some OSes, but that can't be the case. I only got empty results when searching for it. There's also a macro for `ubf_list_atfork` in thread_win32.c, but that doesn't seem to be related here. [below it says my Ruby version is trunk 64156, but I'm compiling on HEAD.] -- https://bugs.ruby-lang.org/ Unsubscribe:
