[Bug c/13395] New: ICE during bootstrap with BOOT_CFLAGS="-O2 -g -fnew-ra -ftracer"

["v dot haisman at sh dot cvut dot cz" <gcc-bugzilla at gcc dot gnu dot org>]

I get this ICE while bootstrapping with those two -f* options. I didn't try any
other combination of these. Preprocessed source is attached.
