The latter, I'd say.  After all, that was one of the reasons for the
change in the breakpoint machinery that now supports multiple
locations for a single breakpoint, right?

We should do these, true; but even if we didn't, the resulting
deficiencies would be much less painful than the current situation.
AFAIK, bugs in constructors and destructors are quite common, so
having no good means to debug them is BAD, IMHO.

Maybe describing the issues here could produce some usefule discusion
about possible design solutions.
