Have you gotten any reports of problems with this patch?  It seems to be sending cc1 into an infinite
loop during the GCC testsuite for me.  I am testing the mips-mti-linux-gnu target and tests like are causing cc1 to suck up all my memory and swap space before the
test times out.

I will keep digging and see if I can figure out what is going on but I wanted to see if anyone else has
reported this problem.
