The gnat compiler has an assert mechanism which will identify source file
name and line numbers. It is used in the compiler code itself to do just
what you describe.
It seems to me that you don't need to know the program unit name if you
know the source code location -- but I haven't seen how, or thought through
whether there is any way to identify the location of the instantiation, if
the assertion fails in a generic unit's code.
Incidentally, you need to turn on a compiler switch to activate the
assertion mechanism.
