Torque Memory Manager asserting on memory free

I get the following assert:

AssertFatal(((bool)((hdr->flags & Array)==Array))==array, avar("Array alloc mismatch. "));

in platformMemory.cc

When I this:

ptr = new int[ intsNeeded ];

			rep_ = (reinterpret_cast<Rep*>( ptr ));

it happens when i free it:

delete [] ptr;

ptr is int * ptr;

it works if I just do a delete ptr...but that memory is lost..?

Using Visual Studio 2003..
