Herve W a949360163 * Allocating 16 bytes more for the MEMALIGN_HACK is enough. There's no ...

need for 1 more extra byte.

* Checking whether the to be allocated size is larger than INT_MAX,
doesn't assure that size+16 bytes for the MEMALIGN_HACK isn't larger
than INT_MAX.

* malloc might return NULL. Checking for it before using that pointer
seems like a good idea.
