both powerpc-apple-darwin8/9 and powerpc-ibm-aix5.3.0.0. On
powerpc-apple-darwin9, these failures appear as...

The failures also happen for powerpc64-unknown-linux-gnu, both -m32 and -m64. 
They start with r142418.

Confirmed.
This is a regression (it should appear in the subject otherwise it would be
missed).
