Using Markus' test case in comment #3 my bisection identified r189686 as the

point where this SEGV was introduced on 4.7 branch:

http://gcc.gnu.org/ml/gcc-cvs/2012-07/msg00591.html

http://gcc.gnu.org/ml/gcc-patches/2012-07/msg00825.html



The corresponding trunk change (r189685) did not cause this test case to fail,

so something else must have changed on trunk to prevent it.

Mainline is fine. Doesn't seem a front-end issue.
