The reason is that the parallel version of sort assumes, in a call to
std:swap at least, that operator* of the iterator returns a reference.
And that is not the case for vector<bool>, of course :(

I'm also seeing another trivial fail:

FAIL: 26_numerics/partial_sum/requirements/explicit_instantiation/2.cc
(test for excess errors)

which seems only due to the missing inclusion of <new>, necessary for
placement new.

While we are at it, I would probably also suggest to qualify such
placement new calls with ::new, per DR 402.

Paolo.
