I got the same error each time. You should be able to reproduce it by
checking out the latest gcc. If that doesn't produce the error, try
checking out sha d8686b0aa945a. I didn't keep that compiler after the tip
of the gcc 4.9 branch worked, so I'd have to rebuild it myself
to reproduce it myself.

Note that compilation of libssp failed with d8686b0aa945a, which is why
I disabled it. I didn't try to build it with 4.9.
