[Fluxus] Fluxus Segmentation Fault

[Chris Targett]

Hi

I've recently managed to build the trunk CVS version of Fluxus in
Ubuntu 8.10. I've used ubuntu packages for almost everything except
ODE, which I compiled from source.

For PLT i've compiled the trunk version in SVN, and also tried using
the version in Ubuntu (which I think is r372), both result in the same
error.

Unfortunatley, when I run the binary I get a segmentation fault. The
backtrace is as follows

xin at bebop:~/fluxus/fluxus$ ./fluxus
Segmentation fault

xin at bebop:~/fluxus/fluxus$ gdb fluxus
(gdb) run

I've tried debugging things further with insight but haven't had much
luck. When setting a watch on 'gc' at line 83 in roots.c insight
reports all the values as
(<type>) Could not read variable object after assignment)
(where <type> is the objects type) Unfortunatley that's the fullest
extent of my debugging skills.

If anybody could shine some light on this issue it would be greatly
appreciated thanks.
