-Wwrite-strings: Don't initialize string command variables to empty string
-Wwrite-strings flags these initializations as requiring a cast.
However, these variables are command variables, and as such point to
heap-allocated memory. The initial allocation is always done when the
corresponding command is registered. E.g.,:
dprintf_function = xstrdup ("printf");
add_setshow_string_cmd ("dprintf-function", class_support,
&dprintf_function, _("\
Set the function to use for dynamic printf"), _("\
Show the function to use for dynamic printf"), NULL,
update_dprintf_commands, NULL,
&setlist, &showlist);
That's why we never reach a bogus attempt to free these string
literals.
So, just drop the incorrect initializations.
gdb/ChangeLog:
2017-04-05 Pedro Alves <palves@redhat.com>
* breakpoint.c (dprintf_function, dprintf_channel): Don't initialize.
* tracepoint.c (default_collect): Don't initialize.
