What does the following mean:
SIGABRT: Abnormal termination
I am not using the abort() or assert() in any of my code. How can I track down what is causing this problem?
Try getting a list of the symbols in your image (from the linker) and putting a breakpoint on anything with "abort" or "raise" in the name.
One possibility, if you're using C++ is that you've managed to call a pure virtual function.
