>Description:
XFree86-4 -configure crashes on systems with i810 video
>How-To-Repeat:
go to system with i810 video (like a Compaq iPaq PC (not handheld)
cd /usr/ports/x11/XFree86-4
make
su
make install
XFree86 -configure
.. XFree86 prints stuff, then exits upon signal 11 ..
>Fix:
You can see that other XFree86-4 drivers have similar code as this diff.
I am in the middle of recreating the reduced diff, after having sprinkled fprintf(stderr) everywhere and also building with -g to get stack traces (I wish that were easier!). So recreated diff I have not yet compiled/tested. i810 may yet have more problems.
