extern int x1f4_copy_expression
    (void **expression, void *x1f4_expression);

The x1f4_copy_expression function creates a copy of the x1f4_expression expression parsed represention and stores its reference at the address indicated by expression.

If the application stacks allocation was requested for the x1f4_expression expression parsed representation the newly created expression parsed representation will not have the expression evaluation required stacks allocated and it will be marked as application stacks allocation requested.
