--- Comment #1 from hst...@quickfur.ath.cx --- If I run the program under gdb and set a breakpoint on the throw, gdb is able to display the nested function as part of the call stack. So obviously all necessary info is there, it's just a matter of incorporating it into the stacktrace generated by the throw. --
