ASAN is also ported to GCC 4.8.
I'm not sure which compiler is more reliable regarding ASAN checks, though.

I also wanted to raise the question of adding '-fsanitize=address'  to
the C flags.
I think fuzzing with ASAN would worth the extra CPU time on buildbots
and I'm even considering
turning ASAN on in the Debian packages by default.

ASAN is basically a borrowed subset of valgrind, so fuzzing with ASAN is not necessary if we can ever get fuzzing with valgrind to work...
