Joel Brobecker 241db429d5 fix "stale cleanup" internal-warning when using "catch assert" command
Trying to insert a catchpoint on all Ada assertions now triggers
the following internal warning regardless of the situation. For
instance, not even debugging any program:

    (gdb) catch assert
    /[...]/gdb/common/cleanups.c:264: internal-warning:
    restore_my_cleanups has found a stale cleanup

This is due to a small bug in the following C++-ification commit:

    commit bc18fbb575
    Author: Tom Tromey <tom@tromey.com>
    Date:   Fri May 18 15:58:50 2018 -0600
    Subject: Change ada_catchpoint::excep_string to be a std::string

The stale cleanup in question is the following one in top.c:execute_command:

    cleanup_if_error = make_bpstat_clear_actions_cleanup ();

This cleanup is expected to be discarded if there are no exception.
There were no GDB exception; however, a C++ exception was triggered,
because we passed NULL as the excep_string argument when calling
create_ada_exception_catchpoint, which is a reference to a const
string. So we get a C++ exception during the std::string constructor,
which propagates up, causing the cleanup to unexpectedly remain
in the cleanup chain.

This patch fixes the immediate issue of the incorrect call to
create_ada_exception_catchpoint.

gdb/ChangeLog:

        * ada-lang.c (catch_assert_command): Pass empty string instead
        of NULL for excep_string argument.

Tested on x86_64-linux, fixes the following failures:

  * catch_assert_if.exp: insert catchpoint on failed assertions with condition
  * catch_ex.exp: insert catchpoint on failed assertions

This also fixes about a dozen UNRESOLVED tests that are a consequence
of the two tests above failing and crashing GDB.

		   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.
