How to prevent Matlab Coder from declaring locals as statics?

Matlab Coder sometimes marks certain local arrays as static. Although this of course saves time in stack setup, it makes the whole function thread-unsafe. How do we suppress this optimization?

(I apologize - I lost my example code.)

You can enable the MultiInstanceCode configuration setting:

That will instead "spill" the statics to a heap-allocated structure that must be passed in when calling the generated entry-point functions. The doc page:

http://www.mathworks.com/help/coder/ug/reentrant-code.html

is the main landing page for that topic and includes links to other pages showing how to call the generated code with this setting enabled.
