Default Re: Segfault with 285.05.09

Has there been any resolution to this problem?

I'm having identical issues with 290.10-13.1 running on OpenSUSE 12.1 with a GeForce GTX 560 Ti.

The segmentation fault is triggered by my own application whilst processing data in several concurrent threads. The segmentation fault only happens if I'm not running the application from GDB, but the backtrace of the core gives me:


Program terminated with signal 11, Segmentation fault.
#0 0x00007ff0c8171a08 in _nv007tls () from /usr/lib64/tls/libnvidia-tls.so.290.10
(gdb) bt
#0 0x00007ff0c8171a08 in _nv007tls () from /usr/lib64/tls/libnvidia-tls.so.290.10
#1 0x00007ff0c8e82ca3 in __nptl_deallocate_tsd () from /lib64/libpthread.so.0
#2 0x00007ff0c8e82f13 in start_thread () from /lib64/libpthread.so.0
#3 0x00007ff0c844f10d in clone () from /lib64/libc.so.6

so, pretty much identical.

As suggested by a previous poster:

export __GL_SINGLE_THREADED=1

seems to prevent the crash.

For me, on this hardware the crash is very reproducible, but on an older computer running 275.21-7.1 I have not seen this issue.

For now I'll use the fix above, but am interested if a resolution to the problem should be found. Also, if useful I can supply code and data that (so far at least) consistently cause the bug to occur.

cheers,

Martin
