But what you describe is a problem with one implementation of Ada (or one
implementation of C -- the same thing might happen between C and Fortran
or C and PL/I).
On VMS the debugger works well between DEC Ada (HP Ada these days) and
other languages. Those of us without a support contract seem to bask
in the glow of others who have reported problems and gotten them fixed.

I have sympathy for the devil's advocate in that regard.
