Issues with multi-iterator list comprehension

[perost]

Implementing List.productMap like this causes issues:

public function productMap<T1, T2, TO>
  "Given two lists and a function, forms the cartesian product of the lists and
   applies the function to each resulting pair.
     Example: productMap({1, 2}, {3, 4}, intMul) = {1*3, 1*4, 2*3, 2*4}"
  input list<T1> inList1;
  input list<T2> inList2;
  input MapFunc inMapFunc;
  output list<TO> outResult;

  partial function MapFunc
    input T1 inElement1;
    input T2 inElement2;
    output TO outResult;
  end MapFunc;
algorithm
  outResult := list(inMapFunc(e1, e2) for e1 in inList1, e2 in inList2);
end productMap;

The issue is that some scodeInst tests fail in BaseHashTable.addNoUpdCheck when adding connectors to the connection set. The is caused by NFConnectionSet.connectorHashFunc, where the first line is:

NFConnect2.CONNECTOR(name = cref) := inConnector;

But cref is {NIL} if output via anyString, so there must be some memory issues somewhere.

The failing testcases are conn3.mo, conn9.mo, ConstantConnector3.mo and expconn4.mo in flattening/modelica/scodeinst, although they all fail in the same way.

I should maybe also point out that the cref in inConnector looks fine in the debugger both before and after the matching, but the cref variable becomes NIL after matching.

Should be fixed in r22350.
