I'm having trouble with the dispatch tests, too. Mine doesn't crash,
but fails due to parse error.
I get a couple more parse errors during make check (in test_prefer). I
suspect this is related to the
recent changes in the parser.
What's worse, simple commands like "help help" fail. Functional forms work.
