I wouldn't bother porting it to C++, it's extremely unlikely to be a FOX 
problem.

Yes, I'm running Red Hat Linux 8.0 on x86.

I can run the code on Windows (either Win2000 or WinXP) but have never 
found a good solution for interactively debugging Ruby extensions (like 
FXRuby) on Windows. The best I can do with Windows (usually) is to just 
add print statements to the C++ source code to try to "triangulate" the 
source of the error ;)

As you've already discovered, the best route is to try to consistently 
reproduce the problem under Linux, where it's generally easier to debug.

OK.

OK. I would still like to actually track down the bug (and not just work 
around it!) but I'm glad the GC.disable trick seems to help for now.
