I can reproduce the ICE with gcc-4.7.2 on armv5tel-linux-gnueabi, sparc64-linux
-m32, x86_64-linux -m32, and m68k-linux.  I haven't checked any other targets.

The ICE stopped on trunk with Richard B's "Make gsi_remove return whether EH
cleanup is required" patch in r186159:
http://gcc.gnu.org/ml/gcc-patches/2012-04/msg00202.html
http://gcc.gnu.org/ml/gcc-cvs/2012-04/msg00108.html

Backporting r186159 and the follow-up fix in r186164 to gcc-4.7.2 eliminates
the ICE there for the four targets mentioned above.

The description of Richard's patch makes it sound more like a cleanup than a
bug fix, so I'm not sure if it actually fixes the bug or just masks it.
