Compiler version: 4.7.0 20110818 (experimental) [trunk revision 177878p2] (GCC)

(where the last two failures are pr47762).
Note that I have to rebuild ppc64/libstdc++-v3 to see the failures disappear;
this is why I think the library is miscompiled.
Would it be possible to infer from the failures what is (are) the file(s) that
is (are) miscompiled?
