[M3devel] compiler problems on Snow Leopard

It is large.
It is more code that could be repeatedly tested, by building the entire "system", for a gradually growing
definition of "system".

We have had a number of problems that only appear in one or two or a few pieces of code.
e.g. the removal of referenced nested functions.
e.g. optimizations causing compilation to fail (which this appears to be as well).

A smaller example would be nice, but that is more work to get.

Rather than cluttering up CVS, why not put it in the bug-tracker?  That's what it is for!

There is a way to get that to show more information..
Or does it already?
