I've compiled Blender 2.63.19 (build50661) on the one PC with Debian Linux OS and it runs there properly. On the other PC with Debian, Blender shuts out with segfault error after opening world tab, or materials, or textures, or system tab in user preferences menu.
blender: segfault at 70 ip 0000000000e3441b sp 00007fffd5278270 error 4 in blender[400000+14ca000]
Version 2.63.17 (build50427) and older versions used to run on both the PCs correctly.
What library or module could cause the problem?
Run Blender in the debugger and get a stack trace. /me bets on the opengl driver.
Thank you. You're right. There was a problem with OpenGL drivers on the "source" PC. Recompiling blender after drivers correction made the deal.
