> Is there any possibility of encountering a function without traceback?
When compiled with option `-qtbtable=none`, the resulting functions do not have a traceback table. As a result, the stack frame cannot be unwound so exception handling is disabled (see man page of [[ https://www.ibm.com/docs/en/xl-c-and-cpp-aix/16.1?topic=descriptions-qtbtable | -qtbtable ]]).
