If you select this option, be aware that a bad_alloc exception might be thrown, per the C++ standard, if an out-of-memory error occurs during the use of new. You must provide code to catch and process the bad_alloc exception in case an out-of-memory error occurs for a new call during construction of a top model object.

If Use dynamic memory allocation for model block instantiation is selected and the base model contains a Model block, the build process might generate copy constructor and assignment operator functions in the private section of the model class. The purpose of the functions is to prevent pointer members within the model class from being copied by other code. For more information, see Model Class Copy Constructor and Assignment Operator.
