Thanks.

I just fixed the last -Wuse-after-free bug.

The ICEs are compiler-side fixes and I don't think we'd want to work around them
in glibc unless the workaround was trivial. I dislike putting -O0 or -O1 in clfags
just to build things, but that's what the downstream distributions need to do
sometimes :-)
