It is not "broken" -- after all, it works as it was intended/designed
when it was introduced, though it is definitely a hack and thus indeed
the message could be improved greatly. :)

As for how to improve it, e.g. Gary suggested the other day to use the
DWARF information to locate the call site.

I guess another way would be to generate different symbol names per
call site, so that we can embed the path and line number into it (more
or less), so that the user at least has a hint, though that may have
disadvantages.

Cheers,
Miguel
