--- Comment #26 from Joost VandeVondele <Joost.VandeVondele at mat dot ethz.ch> 2012-12-19 14:09:54 UTC ---
with Jakob's patch (http://gcc.gnu.org/ml/gcc-patches/2012-12/msg01178.html),
the code runs further, now stopping on another error which seems to be in asan
shadow, and also triggering some kind of an asan internal assert:
