Package: g++-4.2
Version: 4.2.2-5
Severity: wishlist


The warning generated at gcc/cp/call.c:4548 doesn't have a warning type 
associated with it, so there's no way to turn this warning into an
error.

This is a very serious warning, as indicated by the fact that it tells
you the call will abort at runtime.  If a user doesn't notice this
warning, debugging the problem is very difficult.

If one could add something like -Werror=pass-non-POD to the gcc options,
then this would save quite a few headaches here :)

Maybe something along the lines of...
