MallocDebug is a bit to strict when launching an app

Hi,

We are using CW 9.2 for development and are creating a BSD Mach-O target. Metrowerks has supplied a BSD runtime library to link against to satisfy references to items not contained in the Apple dynamic BSD libraries. This works out good except for 2 symbols which are defined in both libraries:

	__isctype()
	__istype()

This of course does not prevent the app from linking and running...only a duplicate reference warning is given. However, when I try to check for leaks using MallocDebug (and launch the app from within MallocDebug), MallocDebug terminates the launch of the app and gives the reason for the error as the warning about the duplicate references. Actually, that is not totally correct...the app "crashes" with a crash report dialog stating this is the reason for the crash but this only happens when launched from MallocDebug so this is where I suspect the problem is. This is totally unnecessary since these warnings have nothing to do with the apps ability to execute. Can you (Apple) apply some more logic to only abort the launch when it really makes sense?

Many thanks!

Alin  Pilkington

P.S. I got around the problem by removing Metrowerks version of these functions and rebuilding their BSD runtime library so this is not a show stopper by any means...
