What exactly scalable_msize does?

Very quick question. Can this fail?

[cpp]ptr = scalable_aligned_malloc(size, alignment);
assert(size==scalable_msize(ptr));[/cpp]

Thanks.

Yes it can.

You can think of scalable_msize as the biggest size for which scalable_realloc returns the same address that it received.
