Hi,

I just compiled XFree86-3.3.5 with pgcc-2.95.1 and noticed that the
X-Server crashes. The problem code lies probably in the directory
xc/programs/Xserver/cfb of XFree86. I tried to compile this code with
different options. Results:

 -O2 -mk6: CRASH
 -O2 -m486: works
 -O2 -fno-schedule-insns2: works
 -O6 -fno-schedule-insns2: works

For this test the rest of the server was compiled with -O. If I compile
the whole X-Server (SVGA) with -O6 the X-Server starts but if
some clients connect it crashes. If I compile with -O3 then the server
dont crash but doesn't find any valid video mode. Very mystical....

Sorry haven't had time yet to do more tests but I hope you can fix this
really soon!

thx,
ron
