https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83015 --- Comment #17 from Jan Hubicka --- Indeed with the configure flags used by your tester it does reproduce. It is difference in inlining priority order, perhaps caused by the badness sanity check (though I fail to see how)

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83015 --- Comment #16 from Jan Hubicka --- ytrium also bootstraps for me. I see you use release checking for stage1 that may be the trigger, I will try it now.

It is bad idea to use periodic benchmarking machine for random bootstraps anyway. Thanks for the info and pointer to working itanium box!

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=83015 --- Comment #11 from Jan Hubicka --- I was able to bootstrap on ia64 box (terbium) shortly before the unwind changes went in without the bootstrap miscompare. So does the miscompare still reproduce for you and if so, would be posible to attach dumps?

Could you please send me the log file or at least the part with error? Is the error still the same or is it different error? Or could you please update the bug with how it fails now?
