The real cause of the ICE in the second test case is Alexandre Oliva's PR
debug/43092 + PR rtl-optimization/43494 fix in r169782:
http://gcc.gnu.org/ml/gcc-cvs/2011-02/msg00325.html
The ICE is masked when the PR37273 missed-optimization fix is present, i.e.
from r169231 to r170199 (exclusive), and from r171111 on current trunk. But
4.6 branch doesn't have the PR37273 fix, so the ICE does occur there.
