Hi,
http://gcc.gnu.org/ml/libstdc++/2007-12/msg00041.html:
some additional details, almost obvious, but anyway.
FAIL: 25_algorithms/partial_sort/moveable.cc (test for excess errors)
This one is because the parallel version of partial_sort doesn't move.
However, the error seems to appear inside the sequential sort routine.
The parallelized routine uses sequential sort, while the sequential
partial_sort does not. And AFAICS the movable test is switched off for
regular sort. So what's the current status? Is sequential "sort"
currently "movable-safe"?
Otherwise, I would suggest to switch off the test for partial_sort
meanwhile.
