Non-returning MetaModelica function with list output returns 0

[perost]

This MetaModelica code:

package test;  
  function f 
    output list<String> outString;
  end f;

  constant list<String> s = f();
end test;

produces this output:

function test.f
  output list<String> outString;
end test.f;

class test
  constant list<String> s = 0;
end test;

I don't really know what's supposed to happen if a function doesn't return anything in MetaModelica, but assigning a list to 0 seems wrong.

The result is almost sane. Boxed 0x00 is the integer zero. The problem is that there is no check for unassigned outputs...
