Great news!

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...

ASAN is only 2x slower (valgrind is 20x slower...) and some bugs is only detect by ASAN...
