I'm studying why we get a regression in backspace_6.f, and
I'm confused by fd_alloc_r_at:
gfc_offset m;
if (where == -1)
where = s->logical_offset;
...
What happens if where != -1 (if we use salloc_r_at)
and we hit the lines
m = where + s->active;
if (s->physical_offset != m && lseek (s->fd, m, SEEK_SET) < 0)
return NULL;
I don't think this is correct.
We only use salloc_r_at form in backspace, so this
might be the reason for some mysterious bugs there.
