[Bug libstdc++/33489] parallel v3: sort assumes that the type of the objects to be sorted have a default constructor

[bkoz at gcc dot gnu dot org]

OK. Now there are tests for all of algorithms for defaultconstructable. As per
20.1, this is not required for template arguments unless the standard
explicitly notes it.

>From this, we can see that the following parallel algorithms have issues with
this:

merge
nth_element
partial_sort
random_shuffle
set_difference
set_intersection
set_symmetric_difference
set_union
sort
stable_sort
partial_sum
