Hi all,
I have been trying to establish a current FG development environment on
a Gentoo Linux system (GCC 4.1.2, glibc 2.6.1, ATI/flgrx). I have
current CVS working copies of plib, OSG, SimGear, and FG. While
everything builds and installs, I get the attached crash when trying to
run fgfs, even after a clean re-build of those libraries.
The first trace (trace.txt) was produced by directly running the fgfs
app, apparently after loading the aircraft data. The second trace
(grind.txt) was produced by valgrind. It successfully works around the
bug and allows fgfs to continue, until valgrind itself segfaults.
Any ideas?
Cheers,
Zach
