Bug in Linux/AXP Mesa 3.0?

["Daniel J. Frasnelli" <dfrasnel csee wvu edu>]

Hey,
	Just playing around with FlightGear 0.57 (www.flightgear.org) on 
my Alpha, and came across a potential bug in Mesa-3.0's gl_Ortho().  I 
first used an install of Mesa 3.0 from the straight source code, but 
installed Designer 7's rpm builds thinking it was a bug not addressed in the 
official version yet.  Attached are a gdb trace and strace showing where 
the program bombs out after starting.
	The system is a DEC 500a, 128M ram running an updated RH 5.2, kernel
2.0.36, egcs 1.0.3a, Mesa-3.0-2 and Mesa-glut-* rpm builds from Peter's site.  
Submitted an inquiry to Curt Olson (FGFS project leader) in hopes that someone
else has seen the problem before.  Obviously I have not provided enough
information here for a bugfix; just want to see if anyone else encountered 
the same problem before I dive headfirst into tracking down the source of 
the trouble.

Thanks,
Daniel
