Mod development: hunting down segfaults

[Risujin]

Whats the best way to hunt down the source of a segfault? What debuggers work with Tremulous?

segfaults happen

Every conceivable debugger that you can think of.
The best debugger for segfaults is one that operates in ring0, or kernelmode.
i.e. SoftIce, rr0d, etc.
(Assuming you're on Win32).

load up the shared object libraries instead of qvms, use your favorite debugger (although i doubt it will work well without dual monitors for client hacks)... or stop dereferencing NULL, i don't even remember the last time i did that in code i wrote (maybe around the time of my printf("hello world\n") days)

Turns out the problem was this line:
*0 = 1;

Actually I'd added new methods of death and forgotten to add *debug strings* for them and it didnt like reading off the deep end of the array.

Good idea about the libraries. QVMs dont make a lot of sense to gdb.
