After typing in ``pwd<RET>'', gdb-debug-log has the following value
(from which you can see the GDB version that I use):
------------------------------------------------------------------------
gdb-debug-log is a variable defined in `gdb-ui.el'.
Its value is
((recv . "(gdb) ")
(recv . "Using host libthread_db library \"/lib64/tls/libthread_db.so.1\".\n")
(recv . "License GPLv3+: GNU GPL version 3 or later

(recv . "GNU gdb 6.7.1\nCopyright (C) 2007 Free Software Foundation, Inc.\n"))
------------------------------------------------------------------------
It seems that the Return key was ignored. After pressing C-c C-c, the
value of gdb-debug-log becomes:
------------------------------------------------------------------------
gdb-debug-log is a variable defined in `gdb-ui.el'.
Its value is
((recv . "(gdb) ")
(recv . "Quit\n")
(recv . "(gdb) ")
(recv . "Using host libthread_db library \"/lib64/tls/libthread_db.so.1\".\n")
(recv . "License GPLv3+: GNU GPL version 3 or later
