Package: libgl1-mesa-swx11 Version: 6.5.1-0.1 Severity: grave Justification: renders package unusable
Steps to reproduce: 1) sudo apt-get install libgl1-mesa-swx11 2) glxgears Expected results: 2) glxgears opens a window and shows an animation Actual results: 2) glxgears does not open a window and dies immediately with "Illegal instruction (core dumped)" More info: 0) Note: This bug seems to happen with any opengl application but I am using glxgears here as a simple testcase. I originally hit this problem when using xmoto 0.2.1-1 1) This bug started to appear after "apt-get dist-upgrade" upgraded libgl1-mesa-swx11 to version 6.5.1-0.1. The bug disappears if I manually install the old version of the package from http://snapshot.debian.net/debian/pool/main/m/mesa/libgl1-mesa-swx11_6.5.0.cvs.20060524-1.1_i386.deb 2) GDB shows the following backtrace: [EMAIL PROTECTED]:~$ gdb glxgears GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.
