This issue is still present in Boost 1.52.

I now believe this to be user error. Specifically, the correct guide to whether input has been consumed should be the iterator supplied to the parser, not the underlying iterator. So it is the lexer's output, not input, iterator I should be checking.

A revised example using the lexer token iterator instead, which produces the expected output (and does not vary with BOOST_SPIRIT_DEBUG)
