The POSIX spec makes it pretty clear that this is not undefined behavior: http://pubs.opengroup.org/onlinepubs/9699919799/functions/posix_memalign.html "If the size of the space requested is 0, the behavior is implementation-defined; the value returned in memptr shall be either a null pointer or a unique pointer." and "The free() function shall deallocate memory that has previously been allocated by posix_memalign()." Geoffrey is right; this is unambiguously a bug in Apple's C library. Nice catch. - Pat ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
