Yes.  The Itanium build doesn't fail in the same
way, but it does fail mysteriously.  The step after
binutils in phase2 is gcc, then coreutils.  The
gcc build completes, then the coreutils construction
fails during the configure phase, thus:

checking for GNU gettext in libc... yes
configure: creating ./config.status
malloc: make_cmd.c:89: assertion botched
malloc: block on free list clobbered
Stopping myself...
E: Child(362) killed by signal 6.

So something is very sick there, too.
