Description Matt Eaton 2003-10-07 21:00:47 UTC 
I emerged glibc-2.3.2-r6 and decided to try out NPTL.. (added "nptl" to use
flags via ufed).

Upon doing this, none of the programs that used the nvidia libGL would run,
immediately segfaulting with similar backtraces:

#0  0x403fb92b in calloc () from /lib/libc.so.6
#1  0x40155ed7 in __nvsym18242 () from /usr/lib/opengl/nvidia/lib/libGL.so.1
#2  0x00000001 in ?? ()
#3  0x0009c244 in ?? ()
#4  0x4068d766 in __nvsym07509 ()
   from /usr/lib/opengl/nvidia/lib/libGLcore.so.1

After re-emerging the same ebuild without NPTL, it works fine.

Reproducible: Always
Steps to Reproduce:
1.USE="nptl" emerge glibc-2.3.2-r6
2.run any opengl program. (first spotted with a gl screensaver)


Actual Results:  
Segfault

works fine over here ...
what if you re-emerge nvidia-glx and restart X ?
Comment 2 Matt Eaton 2003-10-08 09:52:33 UTC 
Yes. Re-emerging nvidia-glx and restarting x/gdm fixed it. I wouldn't have
thought to try this since I thought nvidia-glx were binaries and didn't matter.
I guess the x/gdm restart was the solution.
Comment 3 SpanKY gentoo-dev 2003-10-08 19:17:42 UTC 
nvidia is partly binary partly source
