Patrick Lerda 66313732a7 mesa/program: fix memory leak triggered by parser errors
This change requires the %destructor directive which is supported
by bison or yacc, yacc needs to be compiled with the back-tracking
functionality.

This issue could be checked with the following piglit programs:
glsl-invalid-asm-01, glsl-invalid-asm-02 or vp-bad-program

Direct leak of 5 byte(s) in 1 object(s) allocated from:
    #0 0x7f8dc89050 in __interceptor_strdup (/usr/lib64/libasan.so.6+0x59050)
    #1 0x7f83791cbc in handle_ident ../src/mesa/program/program_lexer.l:129

Source
------

This repository lives at https://gitlab.freedesktop.org/mesa/mesa.
Other repositories are likely forks, and code found there is not supported.


Build & install
---------------

You can find more information in our documentation (`docs/install.rst
<https://mesa3d.org/install.html>`_), but the recommended way is to use
Meson (`docs/meson.rst <https://mesa3d.org/meson.html>`_):

.. code-block:: sh

  $ mkdir build
  $ cd build
  $ meson ..
  $ sudo ninja install


Support
-------

Many Mesa devs hang on IRC; if you're not sure which channel is
appropriate, you should ask your question on `OFTC's #dri-devel
<irc://irc.oftc.net/dri-devel>`_, someone will redirect you if
necessary.
Remember that not everyone is in the same timezone as you, so it might
take a while before someone qualified sees your question.
To figure out who you're talking to, or which nick to ping for your
question, check out `Who's Who on IRC
<https://dri.freedesktop.org/wiki/WhosWho/>`_.

The next best option is to ask your question in an email to the
mailing lists: `mesa-dev\@lists.freedesktop.org
