4009	Array types defined with type are not dealt with correctly in external functions	Francesco Casella	Martin Sjölund	"Consider this simple test case
{{{
model M
  type T = Real [3];

  Real x;

  function f
    input Real x;
    input T t_in;
    output Real y;
    external ""C"";
  annotation(Include = 
    ""
    #include <stddef.h>
    double f(double x, const double *t_in, size_t t_in_size)
    {
    return x + t_in[0] + t_in[1] + t_in[2];
    }
    "");
  end f;

equation
  x = f(time,{1, 2, 3}); 
end M;
}}}

When compiling it, you get this error:
{{{
M_functions.c:17:12: error: too few arguments to function 'f'
   _y_ext = f(_x_ext, (const double*) _t_in_c89);
}}}

Since T is actually an array, according to the Modelica Specification, section 12.9, the above function call should have an extra argument of type size_t containing the size of the array. Apparently, the type declaration masks this information in the code generation."	defect	closed	high	1.11.0	Run-time		fixed		gianluca.bardaro@… luca.bascetta@…
