Which Insight ?

The DebugBreak should have worked. Maybe GDB just continued.

I had some code that generated a STATUS_BAD_STACK type exception. When 
run from cmd the program stopped when the exception occurred. When run 
in GDB it and GDB hung (no ^C support). Looking into GDB I found the GDB 
exception handling loop considered the exception unknown and continued, 
which resulted the app generating the same exception again.

Maybe unknown exceptions should stop GDB. I do not know enough about 
Windows exceptions (SEH) to make this decision.
