Heh - I guess I quoted the spec which allows both.  Several exist.

And of course, the tcmalloc implementation currently used in WTF does this too
(see FastMalloc.cpp)

So - my point remains that we now have different ports using different
allocators that may have different return values for this case.

If you use the USE_SYSTEM_MALLOC in Webkit on mac, you'll get the mac version
of realloc() which won't crash in fastRealloc() in this case.  On the other
hand, if you don't set that env var, you'll use tcmalloc, which will :-)

Seems inconsistent, no?
