Details

Let's say this is called with args of 0x3000, 2, memEnd should end up 0x5000 memStart will get set to 0x0 and memEnd to 0x4000.
In practice this is a inconsequential bug because num pages is only greater than 1 for GCLargeAllocs and the first page will always be within memEnd, so the GC will still mark pointers to this end of range Large allocation. If we had a stack pointer (where we honor interior pointers) to a secondary large page that was at the end of the range like this we wouldn't mark it but that is extremely unlikely in practice.
