hi there,
a lot of people who are using the nvidia closed source driver are having
problems running linux 3d applications. the libGL.so.1 library (linux versi=
on
in /compat/linux/usr/lib) causes almost every linux 3d app to segfault. sin=
ce
the library is the very same one that get's installed under linux the probl=
em
very likely resides in the linuxulator.
i ran two linux games with ktrace. this is the output from linux_kdump. i h=
ope
i copy&pasted the important pieces of the dump that report the crash.

to me it looks like the app crashes during the futex syscall, but i'm far f=
rom
beeing an expert.
it would be great if somebody could take a closer look at this.
cheers.
