Summary0000383: Program behaviour changes when trie string switches are used
DescriptionThe behaviour of the attached program with the attached input differs depending on
whether the predicate cadmium_op_table/2 is compiled into a trie string switch or not.
Steps To Reproduce  $ mmc --make bug
  $ ./bug < bug.inp

yields:

error("Syntax error at token \'main\': operator precedence error", 5)

  $ mmc --no-smart-indexing --make bug
  $ ./bug < bug.inp

yields:

term(varset(var_supply(0), empty, empty), functor(atom("transform"), [functor(atom("="), [functor(atom("main"), [], context("<standard input>", 5)), functor(atom("."), [functor(atom("zinc2merc"), [], context("<standard input>", 5)), functor(atom("high_level"), [], context("<standard input>", 5))], context("<standard input>", 5))], context("<standard input>", 5))], context("<standard input>", 5)))

The latter is the expected output for this program.

Additional InformationThe problem did not exist in rotd-2015-02-20. It exists in rotd-2015-02-27 onwards.
(The change that added trie string switches was committed on 2015-02-24; the next
rotd build was 2015-02-27.)
