Why a bug?  Any malloc system has the right to limit assignment
size.  In this case I expect it is probably using sbrk calls to the
system, and allowing for negative arguments to return core to the
system.  That assignment size is ridiculous on the face of it, and
the test simply exposes a system limit.
