--- Comment #13 from Jonathan Wakely <redi at gcc dot gnu.org> --- The remaining failures are: 25_algorithms/pstl/alg_nonmodifying/nth_element.cc 25_algorithms/pstl/alg_sorting/includes.cc 25_algorithms/pstl/alg_sorting/minmax_element.cc 25_algorithms/pstl/alg_sorting/partial_sort.cc 25_algorithms/pstl/alg_sorting/set_difference.cc 25_algorithms/pstl/alg_sorting/set_intersection.cc 25_algorithms/pstl/alg_sorting/set_symmetric_difference.cc 25_algorithms/pstl/alg_sorting/set_union.cc But they're all timeouts except for partial_sort.cc which is analyzed above, starting from comment 6.
