Of course not, which is why I said "defined" and not "declared".  One
would not set a breakpoint by source co-ordinates of a mere
declaration.  One does that for a function body, which is part of the
definition.

I think my list of "it is ok if ...  heuristic ..."  adequately
communicates acceptance of implementation-imposed approximations, the
natures of which may become known only during implementation.  For
example, organizing the search by compilation unit (CU) file names
instead of all source files is likely quite all right.
