The optimization is sound without -fno-builtin-memset. Otherwise not - why
would that not be in effect for darwin? Can you attach preprocessed source
please?

Just guessing, perhaps Darwin headers define memset using __builtin_memset?
So, perhaps we should ditch #include <string.h> and define the prototypes
ourselves, then it isn't dependent on the target headers.

Seems to fortify by default and thus expose a builtin anyway.

On x86_64-apple-darwin10, with the patch
make -k check-gcc RUNTESTFLAGS="asan.exp --target_board=unix'{-m32,-m64}'"
gives
=== gcc Summary ===
# of expected passes 516
# of unsupported tests 76
and check-g++ gives
=== g++ Summary ===
# of expected passes 810
# of unsupported tests 138
So the patch fixes this PR at least on darwin.
