Keith Packard via Newlib 588a5e1dde libc/stdlib: Use __builtin_mul_overflow for reallocarray and calloc 
This built-in function (available in both gcc and clang) is more
efficient and generates shorter code than open-coding the test.

Sebastian Huber eb14d0cc64 Add BSD-specific reallocarray() 
It is available in FreeBSD, NetBSD and OpenBSD, but not in glibc.  It is
used for example by OpenSSH.
