Calling (Debugging with GDB)Similarly, with a C ++ program it is possible for the function you call via the print or call command to generate an exception that is not handled due to the …

GDB builds a dummy-frame for the inferior function call, and the unwinder cannot seek for exception handlers outside of this dummy-frame. What happens in that case is controlled by …
