--- Comment #12 from Pat Haugen <pthaugen at gcc dot gnu.org> ---
Commentary got lost for prior attachment...

483.xalancbmk from cpu2006 started to fail building on powerpc64[le] with the
subject revision.

Not sure if this should really be directed at pr64988 since it's the same ICE,
but starting here since it was introduced with r221040.
