This doesn't ICE for me though it has a zillion errors.  Can you still
reproduce?

I can't think of patch that would fix ICE like this though...

I no longer have ICE with 4.8, 4.9 or trunk.  There are no errors with
4.8 and 4.9, but a lot with trunk.  Versions are:

gcc version 4.8.3 (Debian 4.8.3-16)
gcc version 4.9.2 (Debian 4.9.2-4)
gcc version 5.0.0 20141212 (experimental) [trunk revision 218651] (GCC)
