Subject: bug#25760: 25.1; Emacs GDB command doesn't honor the "-p" flag
Date: Thu, 16 Feb 2017 12:23:35 -0500

Hi,

        It appears the the Emacs gdb command doesn't honor just
        using the "-p" flag:

0. emacs -Q &

1. M-x gdb
Run gdb (like this): gdb -p 2660
[...]
(gdb) Undefined command: "1-inferior-tty-set".  Try "help".
(gdb) Undefined command: "2-gdb-set".  Try "help".
(gdb) Undefined command: "3-gdb-set".  Try "help".
(gdb) Undefined command: "4-enable-pretty-printing".  Try "help".
(gdb) Undefined command: "5-file-list-exec-source-files".  Try "help".
(gdb) Undefined command: "6-file-list-exec-source-file".  Try "help".
(gdb) Undefined command: "7-gdb-show".  Try "help".
(gdb) Undefined command: "8-stack-info-frame".  Try "help".
(gdb) Undefined command: "9-thread-info".  Try "help".
(gdb) Undefined command: "10-break-list".  Try "help".
(gdb) Undefined command: "11-thread-info".  Try "help".
(gdb) Undefined command: "12-break-list".  Try "help".


      After that, no gdb commands appear to work -- not even
      "quit":

(gdb) quit
Undefined command: "-interpreter-exec".  Try "help".
(gdb) `

      You then have to kill the buffer (C-c k)

      You can, of course use gdb by doing instead:

Run gdb (like this): gdb -i=mi -p 2660

    Thanks.
