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. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=33985
