venus: workaround a gcc-15 dead store elimination (DSE) bug
No issue with clang or gcc-14.x (or earlier versions). The issue only
shows up since gcc-15.1. The compiler somehow fails to consider those
cs helpers dereferencing the pointer from the pNext chain for reads,
and thus has falsely optimized away the pNext store. This change works
around this with a no-op memory clobber.

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

You can find more information in our documentation (`docs/install.rst

.. code-block:: sh

  $ meson setup build
  $ ninja -C build/
  $ sudo ninja -C build/ install

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.
