4300	MetaModelica type checking fail with function pointers	Per Östlund	Martin Sjölund	"This script fails without any error message:
{{{#!mo
setCommandLineOptions(""-g=MetaModelica"");

loadString(""
  uniontype U
    record R
      String path;
    end R;

    function name
      input U u;
      output String name = u.path;
    end name;
  end U;

  function typeCheckFail
  protected
    U u = U.R(\""test\"");
  algorithm
    print(u.name); // Oops, should've been u.path.
  end typeCheckFail;
""); getErrorString();

typeCheckFail(); getErrorString();

In other words, calling a function expecting e.g. a string with a function pointer just silently fails. Using --showErrorMessages shows nothing, but replacing the argument with e.g. an integer does produce the expected error."	defect	new	normal	Future	MetaModelica	v1.12.0
