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': * * * In Emacs 23.1.90.1, tab completion in M-x gud-gdb produces spurious control-M characters; it almost appears as if Ctrl-M is being appended to each symbol name offered for completion. Below, I will give steps to reproduce this behavior, and the results that I observe when following these steps. For this example, any time that you see "^M" (consisting of two characters -- "^" and "M"), please interpret this as the visual representation of the single character Ctrl-M (0x0d). First we will need a C program to debug. I will use the following program: ---------- begin demo2.c -------------- #include static void add_one(int * x) { *x += 1; } static void add_two (int * x) { *x += 2; } int main(void) { int val = 0; add_one(&val); add_two(&val); printf("val=%d\n", val); return 0; } ---------- end demo2.c -------------- STEPS TO REPRODUCE ------------------ (1) Compile demo2.c. gcc -g -o demo2 demo2.c (2) start emacs. emacs -Q -nw demo2.c (3) start the debugger M-x gud-gdb RET Emacs offers the following: "Run gud-gdb (like this): gdb --fullname demo2" Press RETURN to accept the gdb command line. (4) Emacs starts the debugger in buffer "*gud-demo2*", and displays the "(gdb)" prompt. At the gdb prompt enter the commands - b main RETURN - run RETURN (5) Emacs begins to run demo2 under gdb, and breaks in the first line of main. (6) I'd like to set a breakpoint in function "add_one". At the (gdb) prompt in the *gud-demo* buffer, I type "b add TAB". After I press TAB, emacs displays a *Completions* buffer with the following: --------------------------------- In this buffer, type RET to select the completion near point. Possible completions are: add_fdes^M add_one^M add_profil^M add_two^M addcmd^M addr2ascii^M --------------------------------- Note that every symbol is suffixed with "^M" (7) At the (gdb) prompt in the "*gud-demo*" buffer, I type the characters "_o", so that the current (gdb) prompt line contains "b add_o". I press TAB to complete the function name. *gud-demo* completes the function name, and displays --------------------------------- (gdb) b add_one^M --------------------------------- Note that a "^M" was appended to the completed symbol name. (8) At the (gdb) prompt, I type RETURN to create the breakpoint. Emacs responds with --------------------------------- Breakpoint 2 at 0x1f88: file demo2.c, line 4. (gdb) (gdb) --------------------------------- Note that *gud-demo* displays two (gdb) prompts after I press RETURN. (9) At the (gdb) prompt, I type "c RETURN" to continue running demo2. (10) After reaching the breakpoint in add_one, I type "c RETURN" to continue again. demo2 continues executing and exits. After demo2 exits, the *gud-demo2* buffer contains the following contents: --------------------------------- Current directory is ~/ GNU gdb 6.3.50-20050815 (Apple version gdb-768) (Tue Oct 2 04:07:49 UTC 2007) Copyright 2004 Free Software Foundation, Inc.
