(GH-9018) Sometimes some versions of the shared libraries that are part of the traceback are compiled in optimised mode and the Program Counter (PC) is not present, not allowing gdb to walk the frames back. When this happens, the Python bindings of gdb raise an exception, making the test impossible to succeed.
