Ruby 2.2.1 fails to compile with hardened GCC

Description

Hi there!
I've discovered, that Ruby 2.2.1 can't be built using Hardened GCC (4.8 and 4.9).
Probably, that was introduced in that commit: http://svn.ruby-lang.org/cgi-bin/viewvc.cgi/tags/v2_2_1/thread_pthread.c?r1=48992&r2=49578&diff_format=h

Additional info and build logs can be found on downstream bug tracker: https://bugs.gentoo.org/show_bug.cgi?id=542610
(unfortunately, ruby maintainers in downstream are slackers, so I going to report that to upstream myself).

  • Status changed from Open to Feedback

Can't you show the process memory map at the failure?
The call seems to try expanding the stack to 0x7fffff000200, but there needs more margin?

Uh... Sorry for delay! Somewhy I didn't get email notification from your redmine :(

So, I'm not sure, if this is exactly what you asked about (if it is not — I'd be happy to provide output of any gdb command you tell ;) ), but here it is.

Although, that is output from my laptop (with 16GB RAM), and not from the build server of downstream bug reporter. So, memory address you're specified in the question would probably be invalid in that mapping...

Is it any more info I can provide? :)

By the way, I just found (with help of the downstream's Ruby team), that adding -fno-stack-check to the CFLAGS makes it to build fine (and miniruby don't segafults). But I think, it is not the good way to solve this problem :-/

Oh, and yes, adding -fstack-check to the CFLAGS even on non-Hardened system/toolchain reproduce the error ;)

P.S. As for now, latest Ruby-2.1 release is affected too!
