Bugzilla Bug 189205

I use the gnustep overlay and everything emerges OK. But when i try to openapp
an application (Azalea, Gorm, OuterSpace, ProjectManager), i have a
segmentation fault. I have backtraces of all the cored apps (I'll put the
Azalea one in attach). 



Reproducible: Always

Steps to Reproduce:
1.openapp Azalea
2.
3.

Actual Results:  
cedric@endymion ~ $ openapp Azalea
Segmentation fault
cedric@endymion ~ $

Azalea backtrace

Hi Cedric,

Could you please emerge all (or some relevant) packages with
USE="debug" FEATURES="nostrip"?  If you're familiar with gdb, generating a
stack-trace would help.

Thanks!

no need to bug bug-wranglers any more.

ZOMG, your box must me glowin'! 

Sanitize your C[XX]FLAGS and remove the loads of evil crap there before ever
reporting bugs again.(In reply to comment #0)

@grobian - no need to waste time here, this is totally unsupported and
ridiculous.

@jakub: I by chance have waves of segfaults and aborts myself

@cedric: oops, sorry, didn't see you attached backtrace already.

@truedfx: any chance you can say something about that backtrace?

@jakub: C[XX]FLAGS="-march=athlon64 -Os -pipe -ggdb" and doing emerge -e world,
hope it is OK by now ? Sorry for that :-(

@grobian: should i really put debug in my USE flag ? Or is it OK with what you
have ?

Only for gnustep, yes please do.

ok, did rebuild all gnustep with debug (and sanitized CFLAGS) and still seg
fault. new bt in attach

Azalea backtrace (USE=+debug)

I am trying to look into this, but I am not seeing anything obviously wrong.
However, this appears to be specific to libffi, so you could work around it for
now by unsetting the gcc-libffi flag, and using ffcall instead. It won't fix
the bug, but it should allow you to get things working sooner.

hello, first sorry for the late answer (MB died). I can confirm that with the
ffcall lib, all is OK. I can launch every gnustep apps i emerged.
Thank you

Upstream found the problem, patch added to latest gnustep-base-1.16.1

Now libffi support works on amd64 :)
