apitrace dump for glxgears
I am seeing what appears to be the same error. It is reproducible 100%
of the time with glxgears.
I ran glxgears in apitrace (causing a segfault). Attatched is the raw
apitrace.
Is there any other data that I can provide that would be useful?
Hardware is an Intel i7-2860QM.
The segfault is visible in the apitrace replay.
$ apitrace replay glxgears.trace
apitrace: warning: caught signal 11
1357: error: caught an unhandled exception
apitrace: info: taking default action for signal 11
gdb output for glxgears:
Running synchronized to the vertical refresh. The framerate should be
approximately the same as the monitor refresh rate.
Program received signal SIGSEGV, Segmentation fault.
