Summary|Mathematica Plot3D: Crash |Mathematica Plot3D Crash
|in dri2InvalidateBuffers |
--- Comment #1 from Ivan Iakoupov <vox...@gmail.com> 2011-06-01 05:22:51 PDT ---
I did some updates: libdrm, mesa, xf86-videl-intel to recent'ish versions from
master, kernel 2.6.39 (xserver is still 1.9.5 though). Now I cannot reproduce
any crash with that apitrace file. I can still reliably reproduce it using
Mathematica 8 itself though. Just open a new notebook. Type something like
Plot3D[Sin[x*y], {x, 0, 1}, {y, 0, 1}]
Shift+Enter to run and then rotate the resulting plot with the mouse. Upon
releasing the mouse button it crashes. Backtrace is this
Program received signal SIGSEGV, Segmentation fault.

It seems that somehow "GET_CURRENT_CONTEXT(ctx)" a couple of lines above gets a
NULL ctx.
