Question Segfault in libGL.so.1

System: NVidia 7800 GTX 256Mb (SLI system - alienware)
OS: Gentoo Linux
Driver: 1.0.8178

While running an app (my app in openGL), I get segfaults at shutdown after my code is done. Here is a backtrace:

---------------------------------------------
Quiting...

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 16384 (LWP 3089)]
0xb64ae135 in _nv000004gl () from /usr/lib/opengl/nvidia/lib/libGL.so.1
(gdb) bt
#0 0xb64ae135 in _nv000004gl () from /usr/lib/opengl/nvidia/lib/libGL.so.1
#1 0xb6497c26 in _fini () from /usr/lib/opengl/nvidia/lib/libGL.so.1
#2 0x00004000 in ?? ()
#3 0xb7ff6ab4 in _dl_rtld_di_serinfo () from /lib/ld-linux.so.2
#4 0xb6feece9 in exit () from /lib/libc.so.6
#5 0xb6fd95e7 in __libc_start_main () from /lib/libc.so.6
#6 0x080519b1 in _start ()
---------------------------------------------

That "quiting" comes from my main() in C++:

int main(...)
{
...
cout << "Quiting..." << endl;
}

I get this segfault every time.

Any ideas, things I should look at? Need more info?


Thanks in advance.

I will come up with some basic simple code that crashes with the same results. It'll take some time.

Hi,

is you system build with sane CFLAGS?
Are you using nstyx' 'optimized' glibc-ebuild?

Yeah, default Gentoo settings.

No, nothing special as far as I know, default "en" settings.


Hmmm..... The error is now gone. Don't know why. But I'll keep track of the things, and see if anything returns.


Thank you for your time.
