--- Comment #29 from Martin Liška <marxin at gcc dot gnu.org> --- (In reply to Thomas Koenig from comment #28) > https://gcc.gnu.org/ml/fortran/2019-05/msg00173.html reports > the same symptoms for netcdf-fortran-4.4.5, presumably due > to the same issue. > > I'll try to fix that one and then see if the SPEC failure disappears > along with it. > > Martin, one additional question: When you step up from the segfault > in the executable, is an array constructor passed as an argument > somewhere up the call chain? This is what appears to cause the trouble > int netcdf. How can I investigate that?
