Bug 225789 – >=sys-libs/glibc-2.7-r2 : SIGSEGV in gettimeofday

• Product: Gentoo Linux
• Status: RESOLVED NEEDINFO

[Description wbrana 2008-06-10 19:02:10 UTC]

After upgrade from glibc 2.6.1, at least top and glxgears are crashing in funcion gettimeofday 
at startup. It happens also with glibc 2.7-r2.

[Comment 1 Jeroen Roovers (RETIRED) 2008-06-10 19:16:43 UTC]

How about running strace `which top`

[Comment 2 Jeroen Roovers (RETIRED) 2008-06-10 19:41:21 UTC]

Did you upgrade anything else, perhaps sys-kernel/linux-headers? In what order? Did you try if rebuilding sys-process/procps and x11-apps/mesa-progs helps?

[Comment 3 Jeroen Roovers (RETIRED) 2008-06-11 14:39:07 UTC]

You may also want to post dmesg for that system and perhaps your kernel config.

I upgraded in following order
1. linux-headers-2.6.25-r4 
2. glibc-2.8
3. procps with debugging symbols
4. mesa-progs

[Comment 6 wbrana 2008-06-11 19:26:44 UTC]

Crash also doesn't happen with reemerged glibc 2.6.1.

I have had the same thing happen.  My box uses hardened, however.  I believe
this is something related to the kernel.  I have two hardened servers on
glibc-2.7-r1, one with hardened-sources-2.6.24-r2 and the other with
hs-2.6.25-r1, neither experience this.  When I upgraded to hs-2.6.25 (which
pulls in 2.6.25.10) top segfaults on me now.  `strace top` in attachment above.

This should read "When I upgraded to hs-2.6.25-r2..." Apologies.

[Comment 13 wbrana 2008-08-10 14:48:26 UTC]

SIGSEGV disappeared when I compiled glibc 2.8 using gcc 3.4.6 instead of 4.2.4.

[Comment 14 SpanKY 2008-12-07 22:30:17 UTC]

test with glibc-2.8 and gcc-4.3.2 ...

[Comment 15 Suren A. Chilingaryan 2009-02-20 11:53:41 UTC]

I had the same problem. Seems there is Kernel/GLibc incompatibility. Using gettimeofday with not NULL second parameter causes segmentation fault if >=Glibc-2.7 is used with kernel 2.6.25 (haven't check other versions). Kernel upgrade to 2.6.28 have solved problem for me.
