I assume you're on Linux or OSX. (If it's Windows, I'm clueless.)

For me on Ubuntu I type:

$ gdb chuck

and then once it starts up and I get the (gdb) prompt I type:

(gdb) run my_chuck_file.ck

Of course GDB slows down your system, A LOT, but you can keep it running until it hits the segfault. The spew should (hopefully) point toward a specific place in the chuck code that is the problem. (Type q to exit gdb.) You might want to copy the error messages here for the devs to look into.

Never used gdb before, I'll read about this, but any pointers on how to get started?

It's hard to debug segfaults in the ChucK code itself. running gdb chuck
might help narrow down the problem.

Hi,

On a project I'm working on, I sometimes get a "Segmentation fault:
11" error, and the program crashes. But I can't figure out when it
happens, and cannot reproduce it. It's a big project, with many
components communicating via events, and I have no idea who's
triggering the problem. My question is how would you go about
debugging this? Any ideas what can be triggering it? It sounds very
generic...

Probably unrelated, but just in case, I also got this (only once so far):

chuck(22226,0x7fff790ee310) malloc: *** error for object 0x1028f3408:
incorrect checksum for freed object - object was probably modified
after being freed.
*** set a breakpoint in malloc_error_break to debug
Abort trap: 6

Thanks!
Gonzalo
