If I'm debugging code that throws a StackOverflowException, and I add an exception catchpoint, it fails to break at all ... I've had mixed responses from the IDE. In one case, it writes `Stack overflow in unmanaged: IP: 0xa165bfc1, fault addr: 0xbf76ccac
Stack overflow in unmanaged: IP: 0x171b8c, fault addr: 0xbf76bfdc` ... in another case, it shows a few error windows (Screenshot attached). 

The expectation, of course, would be for the debugger to break, and show me the stack trace so that I can debug and see what chain is causing the loop that leads to the stack overflow.

Hi,

Unfortunately, debugging a StackOverflowException is a bit tricky, since invoking the debugger while there is no more stack will most likely just trigger another stack overflow.

Can you get a stacktrace of the stackoverflow, or is that also failing?

Thank you,
