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:
http://www.mathworks.com/help/coder/ug/generate-reentrant-code.html?searchHighlight=multiinstancecode&s_tid=doc_srchtitle
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.
