 Indeed... with some more words that points to useful information... or?

 :-) ...have I heard those words before? Have I spoken in the same manner
myself? ;-)

 Well, there needn't be a _tutorial_ on debugging. Maybe just a link to a
good starting point for understanding gdb/ddd/insight and their usage - for
beginners [1].
 Non-beginners often need just a few words... these words should be added
though - time permitting, as always.

 I've been investigating AmigaOS executables _thoroughly_ and thus know that
some stuff do require intimate knowledge of OS internals.
