First, this is 20-year-old code that hasn't been used much. No excuses, but
I'm not surprised that bad things might happen. When it was written, 78 atoms
was actually a lot for second-derivative analysis.

Second, can you post a test case that fails? We can't help until we can
reproduce the problem....
