1118	Stack overflow when using Matrix in connector	Schubert TUD	Schubert TUD	"Dear all,

when trying to simulate the simple model given below, the omc fails with a stack overflow. 
The model consists of a connector which in turn consists of 3x3 Matrix. The stack overflow \\
occurs if a matrix element is set equal to a ""variable"" expression, like cos(phi) as in the example below.
If every element is a constant (e.g. identity), everything is fine.

Regards,

Christian

PS: Here is the model:

connector con 
  Real A[3,3]; 
end con;

model Test  
  Real phi(start=1);
  con o;
equation
  der(phi)=1;
  o.A = {{cos(phi),0,0}, {0,1,0}, {0,0,1}}; 
end Test;

PPS: Find attached the out.txt which shows all errors thrown by the omc."	defect	closed	high		Instantiation	1.4.5	worksforme		Schubert TUD
