*Using variable length arrays*

Type: ``bool``

Help
====

.. code-block:: none

    Using VLA slightly decreases stack usage in some cases it may not be
    supported. Note that VLA are used for arrays which size is resolved at
    compile time so at runtime arrays have fixed size.

Direct dependencies
===================

\ :kconfig:`LOG <CONFIG_LOG>`

*(Includes any dependencies from ifs and menus.)*

Default
=======

- y if !\ :kconfig:`MISRA_SANE <CONFIG_MISRA_SANE>`
