re PR libfortran/92100 (Formatted stream IO irreproducible read with binary data in file)
2019-11-24 Jerry DeLisle <jvdelisle@gcc.ngu.org>
PR fortran/92100
io/transfer.c (data_transfer_init_worker): Use fbuf_reset
instead of fbuf_flush before the seek. Note that fbuf_reset
calls fbuf_flush and adjusts fbuf pointers.
