| Summary | 0000221: ho specialization bug | ||||
| Description | The attached program produces the wrong output when compiled with --optimize-higher-order. It should output "ho2", but instead outputs "ho1". In do_stuff it is specializing P to ho1, when it shouldn't. Here is the relevant bit of the hlds dump for stage 135: :- mode do_stuff((builtin.in), (builtin.di), (builtin.uo)) is det. bug.do_stuff(Maybe, STATE_VARIABLE_IO_0, STATE_VARIABLE_IO) :- ( % cannot_fail switch on `Maybe' % Maybe has functor maybe.no/0 P = bug.ho1 ; % Maybe has functor maybe.yes/1 P = bug.get_ho2 ), bug.ho1(STATE_VARIABLE_IO_0, STATE_VARIABLE_IO). | ||||
