Thanks for the pointer to -Dr. I guess this is different from use re 'debug' as the latter works but I will have to recompile perl with -DDEBUGGING to try -Dr.

Pointers to any documentation that will help me understand the (I assume) non-trivial output that will be produced would be greatly appreciated. I know of perlreguts, though I'm not very familiar with it and will have to look again.

When the only tool you know is gdb everything looks like an object module, and your head hurts
