I found an obvious bug in Ada aggregate expression handling:
if (vvo != nullptr)
error (_("Invalid record component association."));
name = vvo->get_symbol ()->natural_name ();
Here the code errors when vvo is not null -- and then proceeds to use
vvo.
This hasn't caused a crash because, I believe, there's currently no
way to reach this code in the null case. However, I'm not really
willing to assert this...
Fixing this shows another bug, which is that due to the way the parser
works, a field name in an aggregate expression might erroneously be
fully qualified if some global variable with the same base name
exists.
The included test case triggers both bugs. Note that the test
includes a confounding case for array aggregates as well, but as these
are harder to fix, I've left it as kfail.
As this is Ada-specific, and has already been tested internally at
AdaCore, I am checking it in.
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.
