Very Computer

Hi,

I have no idea how to debug this so some insight would be very helpful.
Quake3 arena is crashing with 2.4.8 and 2.4.8-ac1.

I'm pretty sure it's related to the emu10k1 changes because the last
output is:

...loading 'scripts/sky.shader'
...loading 'scripts/test.shader'
----- finished R_Init -----

------- sound initialization -------
------------------------------------
Received signal 11, exiting...

It works fine with 2.4.7 and -ac series.

Here's my system info:

Mandrake 8.0

Linux version 2.4.8-ac1 (r...@localhost.localdomain) (gcc version 3.0) #1

Hrm, I upgraded from 2.4.7-ac11 + EMU10K1 CVS v0.15 diffs to 2.4.8 + Rui's
patch + Juha's AC3 SMP fix + Andrea's 2.4.8aa1, and quake3 1.29h PR works
fine here. I did compile with gcc version 2.95.4 20010721 (Debian pre
release), however.
