Anything that doesn't use overcommit. Windows is the big obvious one here. Also
various UNIX-like things, and even Linux is not guaranteed to return non-NULL,
depending on how the kernel is set up (e.g. on some RHELs I think, or on
plenty of embedded setups.) 

Some libcs will fail if the requested size is outside of the allowed range.

In any case, the checks should be done.
