Confirmed on powerpc-apple-darwin9. Compiling the preprocessed code with '-O2
-m64' gives the ICE, but not when using '-O2' nor '-O1 -m64'.

I successfully bootstrapped revision 186090 on powerpc-apple-darwin9. From
http://gcc.gnu.org/ml/gcc-testresults/2012-04/msg00234.html it seems also fixed
for powerpc64-unknown-linux-gnu. So this PR could probably closed as fixed.
