--- Comment #13 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> --- Author: jvdelisle Date: Wed Nov 27 00:50:51 2019 New Revision: 278753 URL: https://gcc.gnu.org/viewcvs?rev=278753&root=gcc&view=rev Log: 2019-11-26 Jerry DeLisle <jvdeli...@gcc.ngu.org> Backport from mainline PR fortran/92100 io/transfer.c (data_transfer_init): Use fbuf_reset instead of fbuf_flush before the seek. Note that fbuf_reset calls fbuf_flush and adjusts fbuf pointers. gfortran.dg/streamio_18.f90: New test.
