Upon selecting the "OpenGL Spectrum Analyzer" visualization plugin in XMMS, it crashes with a floating point exception.

If you suspect it may be CFLAGS, that problem is easy enough to eliminate. Change your CFLAGS to something innocent (like "-O2 -pipe") and recompile xfree and xmms, along with whatever other program you may be using for 3D acceleration.
This looks like a problem with GL / drivers and not xmms. Are you still having the problem?
Marking it invalid, reopen if this is still an issues/pops up again.
