<pre>ASAN's posix_memalign() should return ENOMEM when the allocation fails due to
lack of memory.
I can reproduce this reliably by making a huge allocation (e.g. 2^48 bytes)
with ASAN_OPTIONS including allocator_may_return_null=1. A null pointer is
returned via the output argument but the return value is 0 (which means
success).</pre>
