Description Michael Schwendt 2005-08-31 00:20:59 UTC 
Similar symptoms as in bug 3076, but different hardware different
driver (Matrox Millennium G400).

Fedora Core 4 bug report here:
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=166629

In search of ways on how to make Amarok (in Fedora Extras) crash,
I stumbled into this inside and outside of gdb, clicking into the
player window, switching through the GL based graphical analysers:

[...]
Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread -1209018688 (LWP 3745)]
0x04bb1dfc in _mesa_test_os_sse_exception_support ()
   from /usr/X11R6/lib/modules/dri/mga_dri.so
(gdb) c
Continuing.

Program received signal SIGSEGV, Segmentation fault.

$ rpm -qf /usr/X11R6/lib/modules/dri/mga_dri.so
xorg-x11-6.8.2-37

System is a fully up-to-date FC4.

Comment 3 Michael Schwendt 2005-09-14 02:42:32 UTC 
I mentioned the similarity with bug 3076 in the original comment.
Comment 4 Ian Romanick 2005-10-17 22:04:14 UTC 
Reassigning to Mesa as this appears to be a problem in the DRI driver.
