Summary: Segfault after glXMakeCurrent
Product: Mesa
Version: 6.5
Platform: PC
OS/Version: Linux
Status: NEW
Keywords: have-backtrace
Severity: normal
Priority: P2
Component: GLX
AssignedTo: mesa3d-dev@lists.sourceforge.net
ReportedBy: [EMAIL PROTECTED]
When using pd with Gem OpenGL extension I get segfault when destroying or
closing the GL window. I am using Fedora Core 6, with mesa 6.5.1 and Radeon
Mobility 9000. There is no problem closing or destroying the GL window using
mesa 6.4.2 version of libGL.
Here's the gdb backtrace:
