Thanks,
My crash is not from an end customer. It is from me during
development. I don't have a second Mac to attach for a debugger.
But if I simply knew which of my own functions the crash
occurred in, I'd be farther along (and it is my own function).
The panic text reports the
function addresses, what I'd like to see is a text representation
of my drivers symbol table so that I can figure out what
function is at which address.
Every compiler I've ever used
was able to produce a human readable symbol table map.
But I can't see how to do that with the Project Builder
compiler.
