--- Comment #5 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- I confirmed the segfault mentioned. The gfc_unit *u is not set. I will fix that first inquire_via_unit (iqp=iqp@entry=0x7fffffffc8e0, u=u@entry=0x0) at ../../../libgfortran/io/inquire.c:348 348 if (!ASYNC_IO || u->au == NULL) We need to guard that with an error message I suspect.
