*Always use runtime message creation (v2)*

Type: ``bool``

Help
====

.. code-block:: none

    If enabled, runtime method is always used for message creation. Static
    creation relies on compiler being able to optimize and remove code
    based on information known at compile time. It is recommended to
    enable this option when optimization is disabled because some compilers
    (seen on arm_cortex_m and x86) were using unrealistic amount of stack
    for dead code. Option applies to v1 as well because distinction
    between versions is done by the compiler.
