[ruby-core:119139] Re: CPU-bound load affects the timeout thread

On a side note, it seems like the following commit: https://github.com/ruby/ruby/commit/ac244938e8b97c8bd42d1dc8ed820091e6ef5537... breaks the VMDEBUG... feature? FILE * is still not passed to rb_vmdebug_debug_print_pre(), rb_vmdebug_debug_print_post() and possibly some other functions: https://github.com/ruby/ruby/blob/ac244938e8b97c8bd42d1dc8ed820091e6ef5537/v... Passing stderr supposedly should fix the issue, but then make fails with: linking miniruby make: *** [uncommon.mk:1335: builtin_binary.inc] Illegal instruction (core dumped) make: *** Waiting for unfinished jobs.... make[1]: Leaving directory '/ruby'
