Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the emacs-pretest-bug@gnu.org mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug.  If you can, give
a recipe starting from `emacs -Q':

                                 * * *

STEPS TO REPRODUCE
------------------

(1) Start emacs with the command line "emacs -nw -Q foo.c".

     foo.c should be a new file, which does not exist prior to starting
     emacs.

(2) Type "#include <stdio.h>" and RETURN

(3) Type RETURN to leave a blank line

(4) type "static void add_one(int * x) {" and RETURN

(5) type "*x += 1;" and RETURN

(6) type "}" and RETURN (to close the function definition)

NOTE: the statement written in step (5) is left-aligned to column
zero.  The statement should be indented.

(7) Place point in column zero of the line "*x += 1;".  Press TAB.

     Before pressing TAB, "*x += 1;" is aligned to column zero.  After
     pressing TAB, "*x += 1;" is still aligned to column zero.  TAB did
     not indent the statement.

(8) Type "C-x h TAB" (i.e., to select and re-indent the entire
     buffer).

     The minibuffer displays "Indenting region... done".  However, the
     statement "*x += 1;" is still aligned to column zero.

After step 8, buffer "foo.c" looks like this:
---------------------------------
#include <stdio.h>

static void add_one(int * x) {
*x += 1;
}
---------------------------------
NOTE: the fourth line is not indented (but it should be).


NOTES:
-----

In buffer "foo.c",  "M-x describe-key RET TAB" produces:
---------------------------------
TAB runs the command c-indent-line-or-region, which is an interactive
compiled Lisp function in `cc-cmds.el'.

It is bound to TAB, <menu-bar> <C> <Indent Line or Region>.

(c-indent-line-or-region &optional ARG REGION)

Indent active region, current line, or block starting on this line.
In Transient Mark mode, when the region is active, reindent the region.
Otherwise, with a prefix argument, rigidly reindent the expression
starting on the current line.
Otherwise reindent just the current line.
---------------------------------

NOTE: In step (8), when the entire buffer was selected, with transient
mark mode enabled, TAB did not re-indent the region correctly.

Likewise, in step (7) TAB did not re-indent the current line
("Otherwise reindent just the current line"). 




In buffer "foo.c",  "M-x desribe-mode" produces:
---------------------------------
Enabled minor modes: Abbrev Auto-Composition Auto-Compression
Auto-Encryption File-Name-Shadow Font-Lock Global-Auto-Composition
Global-Font-Lock Line-Number Menu-Bar Mouse-Wheel Tool-Bar Tooltip
Transient-Mark

(Information about these minor modes follows the major mode info.)

C/l mode:
Major mode for editing K&R and ANSI C code.
To submit a problem report, enter `C-c C-b' from a
c-mode buffer.  This automatically sets up a mail buffer with version
information already added.  You just need to add a description of the
problem, including a reproducible test case, and send the message.

To see what version of CC Mode you are running, enter `M-x c-version'.

The hook `c-mode-common-hook' is run with no args at mode
initialization, then `c-mode-hook'.

   [rest of describe-mode output omitted]
---------------------------------




M-x c-version produces the following:
---------------------------------
Using CC Mode version 5.31.8
---------------------------------

Finally, the same behavior occurs when emacs is started as "emacs -Q"
(i.e., if the -nw option is ommitted from the command line).

please include the output from the following gdb commands:
     `bt full' and `xbacktrace'.
