RE: garbage colleciton crash

["Kevin Baca" <lualist@...>]

A more primitive approach that I use is to pepper my code with calls to
_CrtCheckMemory(), which checks the debug heap for a few types of memory
corruption.

It can help pinpoint the area of code where and the time when the
corruption occurs.

_CrtCheckMemory() is part of the debug runtime libs with visual studio,
but I would think that Metrowerks has something similar.
