Philippe Waroquiers 4a8110007b Fix a (one shot small) leak in language.c
Valgrind detects the following leak:
==28395== VALGRIND_GDB_ERROR_BEGIN
==28395== 5 bytes in 1 blocks are definitely lost in loss record 20 of 2,770
==28395==    at 0x4C2BE2D: malloc (vg_replace_malloc.c:299)
==28395==    by 0x41D9E7: xmalloc (common-utils.c:44)
==28395==    by 0x78BF39: xstrdup (xstrdup.c:34)
==28395==    by 0x51F1AC: _initialize_language() (language.c:1175)
==28395==    by 0x6B3356: initialize_all_files() (init.c:308)
==28395==    by 0x66D194: gdb_init(char*) (top.c:2159)
==28395==    by 0x554C11: captured_main_1 (main.c:863)
==28395==    by 0x554C11: captured_main (main.c:1167)
==28395==    by 0x554C11: gdb_main(captured_main_args*) (main.c:1193)
==28395==    by 0x29D837: main (gdb.c:32)
==28395==
==28395== VALGRIND_GDB_ERROR_END

This is a very small leak (1 block/5 bytes), happening only once
per GDB startup as far as I can see. But this fix make the nr of leaking
GDB in the testsuite decreasing from 628 to 566.

It is unclear why a xstrdup-ed value is assigned to 'language'
at initialization time, while a static "auto" string is assigned
as part of the set_language_command.
So, that shows that it is ok to initialize 'language' directly
with "auto".
Also, I cannot find any place where 'language' is xfree-d.
No leak was detected for 'range' and 'case_sensitive', but
similarly, no indication why a static string cannot be assigned.

Regression-tested on debian/x86_64.
Also, full testsuite run under valgrind, less tests leaking,
and no dangling pointer problem detected.

2018-12-05  Philippe Waroquiers  <philippe.waroquiers@skynet.be>

	* language.c (_initialize_language): Fix leak by assigning
	a static string to language.  Same for range and case_sensitive,
	even if no leak is detected for these variables.

		   README for GNU development tools

This directory contains various GNU compilers, assemblers, linkers, 
debuggers, etc., plus their support routines, definitions, and documentation.

If you are receiving this as part of a GDB release, see the file gdb/README.
If with a binutils release, see binutils/README;  if with a libg++ release,
see libg++/README, etc.  That'll give you info about this
package -- supported targets, how to use it, how to report bugs, etc.

It is now possible to automatically configure and build a variety of
tools with one command.  To build all of the tools contained herein,
run the ``configure'' script here, e.g.:

	./configure 
	make

To install them (by default in /usr/local/bin, /usr/local/lib, etc),
then do:
	make install

(If the configure script can't determine your type of computer, give it
the name as an argument, for instance ``./configure sun4''.  You can
use the script ``config.sub'' to test whether a name is recognized; if
it is, config.sub translates it to a triplet specifying CPU, vendor,
and OS.)

If you have more than one compiler on your system, it is often best to
explicitly set CC in the environment before running configure, and to
also set CC when running make.  For example (assuming sh/bash/ksh):

	CC=gcc ./configure
	make

A similar example using csh:

	setenv CC gcc
	./configure
	make

Much of the code and documentation enclosed is copyright by
the Free Software Foundation, Inc.  See the file COPYING or
COPYING.LIB in the various directories, for a description of the
GNU General Public License terms under which you can copy the files.

REPORTING BUGS: Again, see gdb/README, binutils/README, etc., for info
on where and how to report problems.
