This was fixed for gcc-4.7.0 by r177658:
http://gcc.gnu.org/ml/gcc-cvs/2011-08/msg00672.html
http://gcc.gnu.org/ml/gcc-patches/2011-08/msg00353.html
The patch applies cleanly to 4.6.3 and cures the ICE on this test case. I
haven't tested the backport beyond that.
For 4.6.3 you can also avoid the ICE by reducing the optimization level to -O2.
