--- Comment #11 from Dominique d'Humieres <dominiq at lps dot ens.fr> --- The test in comment 7 compiles without any warning with gfortran 6.4.1 and before. In a similar way the original test starts to give the warnings pr77504.f90:10:0: Warning: 'help_text.dim[0].lbound' is used uninitialized in this function [-Wuninitialized] pr77504.f90:10:0: Warning: 'help_text.dim[0].ubound' is used uninitialized in this function [-Wuninitialized] for gfortran 7 and above.
