It's a HWI32 bug.
The ICE reproduces on x86 with 4.6 branch if you build a 32-bit compiler that
targets 32-bit x86; passing -m32 to a 64-bit compiler won't trigger it.
The ICE was silenced on 32-bit x86 for 4.7 by r176871:
http://gcc.gnu.org/ml/gcc-cvs/2011-07/msg01139.html
which is when HJ made 32-bit x86 HWI64.
The ICE reproduces with current 4.7 and 4.8 in 32-bit compilers with HWI32
targets; for instance an i686 to m68k linux cross says:
pr55355.cc: In member function 'void C::funcC()':
pr55355.cc:34:1: internal compiler error: in tree_low_cst, at tree.c:6603
