--- Comment #2 from Jonathan Wakely <redi at gcc dot gnu.org> ---
More likely is that OS X has a non-conforming aligned_alloc, similar to AIX:
#if _GLIBCXX_HAVE_ALIGNED_ALLOC
# ifdef _AIX
/* AIX 7.2.0.0 aligned_alloc incorrectly has posix_memalign's requirement
* that alignment is a multiple of sizeof(void*). */
if (align < sizeof(void*))
align = sizeof(void*);
# endif
/* C11: the value of size shall be an integral multiple of alignment. */
sz = (sz + align - 1) & ~(align - 1);
#endif
Please attach the output of compiling your example with -E -dM so I can see
which macros are defined.
