--- Comment #3 from Tobias Burnus <burnus at gcc dot gnu.org> --- The patch of comment 0 re-appeared in slightly different flavor for PR99125 (https://gcc.gnu.org/pipermail/gcc-patches/2021-February/565768.html); thus, that part is now fixed. Still, the tests in the testcase still fail as before. (Except: sub2 fails with '4' not '1' (typo) and '(2)' does not segfault at run time (at the moment) but just fails with 'stop 4'.)
