Summary: NPE in FormalParameters.resolve

Initial Comment:
After CVS updating to get the fix for #976723, received
the following error while trying to compile this code:

(int,int) foo((?int,?int) tup) 
{
  (?int a, ?int b) = tup;
  return (a || 0, b || 0);
}

void main(String[] args) {
  println(foo((null, 3)));
}

C:\src\nice>nicec -a test test
nice.lang: parsing
test: parsing

An exception has occured in the compiler
