--- Comment #2 from Stanislav Blinov <stanislav.blinov at gmail.com> ---
>From http://man7.org/linux/man-pages/man3/malloc.3p.html :

Upon successful completion with size not equal to 0, malloc() shall return a
pointer to the allocated space. If size is 0, either a null pointer or a unique
pointer that can be successfully passed to free() shall be returned. Otherwise,
it shall return a null pointer and set errno to indicate the error.

I.e. just checking for 0 result is insufficient to make the failure call.
