Application Verifier break message

Extreme size request.

Probable cause

This break will be generated if in a HeapAlloc() or HeapReAlloc() operation the size of the block is above any reasonable value. Typically this value is 0x80000000 on 32-bit platforms and 0x8000000000000000 on 64-bit platforms. This error is hit when the allocation size is a negative number treated as a positive one.
