  This is not a bug.  fllwfuncHnew's first argument
should be a VECTOR with elements a and b (rather than
passing a and b as separate arguments.  From ?nlm:

     f: the function to be minimized.  [...]
          This should be a function of a vector of the
          length of 'p' followed by any other arguments specified by
          the '...' argument.

   Please try a little harder to make sure that
a bug is a bug before reporting it as such ...
