Jerry DeLisle <jvdelisle at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |pault at gcc dot gnu.org --- Comment #3 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Regression testing completed. The offending patch is the DTIO changes on 8-31-2016. Looking at the tree dump we see things like: dt_parm.4.common.iostat = &ios; dt_parm.4.namelist_name = &"test"[1]{lb: 1 sz: 1}; dt_parm.4.namelist_name_len = 4; dt_parm.4.common.flags = 33056; _gfortran_st_set_nml_dtio_var (&dt_parm.4, &x, &"x"[1]{lb: 1 sz: 1}, 4, 0, 8, 0B, 0B); _gfortran_st_set_nml_dtio_var (&dt_parm.4, &y, &"y"[1]{lb: 1 sz: 1}, 4, 0, 8, 0B, 0B); dt_parm.4.common.unit = io; _gfortran_st_read (&dt_parm.4); _gfortran_st_read_done (&dt_parm.4); } { Where this case does not involve dtio.
