This is not a *good* solution, but it might help. G++ routes `new' calls to
`malloc'. With a little linker magic, I believe you can get all `malloc'
calls rerouted to your own routine. See the `--wrap' option to `ld'.

This doesn't allow you to get the line numbers, though. I suppose if you
were *really* masochistic, you could make the user compile with `-g', then
look at the stack for the address of their function and use the debug info
to translate that into file and line number. `libdbg.a' has some routines
that might help with that.
