I just checked in a change which fixes the case I'm aware of where folding
could create non-gimple code (which would lead to the kind of failure you
are seeing).

 >/usr/local/src/gcc-binutils/branch/objdir/i686-pc-cygwin/libstdc++-v3/include
 >/ext/pool_allocator.h: In member function `_Tp* __gnu_cxx::__pool_alloc<_Tp>:
 >:allocate(size_t, const void*) [with _Tp = wchar_t]':
 >/usr/local/src/gcc-binutils/branch/objdir/i686-pc-cygwin/libstdc++-v3/include
 >/ext/pool_allocator.h:299: error: Invalid operand to binary operator
 >(int<D2>)__n<D10755>_17;

If you could re-test with an updated compiler it would be greatly appreciated.
