  33    ARGS is a vector of values of arguments (NARGS of them).  FUNCTION
  34    is a value, the function to be called.  Returns a value
  35    representing what the function returned.  May fail to return, if a
  36    breakpoint or signal is hit during the execution of the function.
  37
  38    DFEAULT_RETURN_TYPE is used as function return type if the return
  39    type is unknown.  This is used when calling functions with no debug
  40    info.
