--- Comment #4 from Jakub Jelinek <jakub at gcc dot gnu.org> --- The testcase has been changed on the GCC side after lengthy discussion on it back in 2014, the result has been that the testcase is invalid, but there is a desire to make it work somehow in the future. Nothing happened in that area in OpenMP 4.5 though.
