Description pawan 2015-10-15 09:11:36 UTC

We have cfd code which use VTK for dumping image . We have compiled VTK with onscreen rendering without mesa and offscreen rendering with Mesa. One with onscreen rendering worked fine but one with offscreen rendering with mesa is giving segmentation fault for certain case. It worked fine for many but with one case it fail randomly. Following is message , i am getting from Mesa

It failed both using system(opensuse 13.2) installed mesa or other mesa 11.0.3 and other 10.3.2 . Similar error occur in Centos 6.6.
