Bug 33265 – emerge emacs fails with CFLAGS="-fstack-protector"

• Status: RESOLVED TEST-REQUEST
• Product: Gentoo Linux

[Description Spider (RETIRED) 2003-11-11 17:19:49 UTC]

CFLAGS="-O2 -march=i686  -fstack-protector -fomit-frame-pointer"
gcc version 3.2.3 20030422 (Gentoo Linux 1.4 3.2.3-r2, propolice)


Actually, it gets an Internal Compiler Error.

ping?

[Comment 2 Jeremy Maitin-Shepard 2003-11-30 16:14:14 UTC]

The nature of an internal compiler error is that ultimately, it is a compiler bug, not a problem with the source code.  A possible workaround would be for the emacs ebuild to filter out the -fstack-protector flag.  It is also possible that this is fixed with future versions of GCC.

[Comment 3 Jeremy Maitin-Shepard 2003-11-30 16:15:46 UTC]

(Future or later versions of GCC, that is)

[Comment 4 Mamoru KOMACHI (RETIRED) 2003-11-30 22:40:14 UTC]

I could reproduce the problem (internal compiler error at xterm.c)
with gcc-3.2.3-r3 and glibc-2.3.2-r3, so I filtered out
-fstack-protector from emacs-21.3-r1.ebuild for the moment.
Could hardend herd people look into the problem? Thanks.

i will test this ebuild in a week or two when the ssp.o -nostdlib/-nostartfiles fix with hardened-gcc comes around

thanks,

Alex

[Comment 6 Alexander Gabert (RETIRED) 2003-12-01 15:11:03 UTC]

works for me with gcc-3.3.2-r3 and hardened-gcc

can you test with this gcc please?

TIA,

Alex
