Subject: [Bug libfortran/25139] [4.1/4.2 regression] "Invalid argument" error on I/O
Date: Sat, 10 Dec 2005 16:39:00 -0000 [thread overview]
Message-ID: <20051210163926.16075.qmail@sourceware.org> (raw)
In-Reply-To: <bug-25139-10129@http.gcc.gnu.org/bugzilla/>
------- Comment #6 from fxcoudert at gcc dot gnu dot org 2005-12-10 16:39 -------
I found the problem in the second one, which is fixed by the one-line patch:
Index: io/file_pos.c
===================================================================
--- io/file_pos.c (revision 108353)
+++ io/file_pos.c (working copy)
@@ -109,13 +109,14 @@
length = sizeof (gfc_offset);
- p = salloc_r_at (u->s, &length,
- file_position (u->s) - length);
+ /* length is modified by this function call, and most probably
+ set to zero. */
+ p = salloc_r_at (u->s, &length, file_position (u->s) - length);
if (p == NULL)
goto io_error;
memcpy (&m, p, sizeof (gfc_offset));
- new = file_position (u->s) - m - 2*length;
+ new = file_position (u->s) - m - sizeof (gfc_offset) - length;
if (sseek (u->s, new) == FAILURE)
goto io_error;
(well, more than one line since I added a comment so that we don't do this
mistake again). Since this does not fixed the other problem, I filed it
separately under PR 25340.
