It depends on what kind of crash bug is in guestion...

If demo just freezes, I think "profile" (or "dspprofile" for DSP) command
is IMHO best way to find out what it's doing and where in the code.

After that shows where code is running, one can disassemble those
places to see what it actually does.

If it's checking some register, then one could do e.g. register value
change tracing.

That I don't have experience with, but I would assume that search
(which debugger is currently missing) to be useful...
