Re: Crash in xserv 4.3.0-40

Ãyvind,

There are two problems with your current method of testing:

1) You are running under gdb, which will slow things down and affect the 
likelyhood of a race condition causing a crash.

2) The code in hw/xwin from the xorg CVS is slightly different than the 
code in XFree86-xserv-4.3.0-41.


To work around these issues, try the following:

1) Run you XWin.exe build without gdb until you can confirm that the 
problem occurs again.

2) Then, after you have confirmed that XWin.exe still has the problem, 
run it under gdb and hope that it can be reproduced again.  :)

3) Consider grabbing the XFree86-xserv-4.3.0-41 source code release that 
I posted a link to in the announcement (it just has files from hw/xwin). 
 Go into your source tree and do the following:

a) cd xc/programs/Xserver/hw

b) mv xwin xwin-cvs

c) mkdir xwin

d) cd xwin

e) tar xjf path_to_file/xwin-20040115-0100.tar.bz2

f) cd build/std/programs/Xserver/hw/xwin

g) lndir xc/programs/Xserver/hw/xwin

h) make Makefile

i) make depend

j) make clean

k) make

l) cd ../.. && make XWin.exe

That should give you a build that more closely resembles the 4.3.0-41 
release.
