#12208: Lexer does not work with boost::spirit::istream_iterator

     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  wave
  Version:  Boost 1.61.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+---------------------
 According to the documentation, any forward iterator should be usable for
 the input stream iterator.  boost::spirit::istream_iterator is a forward
 iterator, yet I find boost::wave::lexing_exception is called when it is
 used instead of std::string_iterator.  Further, the Changelog has this to
 say:

 TODO (known issues):
 ...
 - Fix the re2c lexer for iterators others then string::iterator (or more
   generally for iterators, which aren't random access iterators)

 which implies that this is a known problem.

 Either the documentation should indicate that a random access iterator is
 required (and this should be enforced with an iterator traits check), or
 the code should be fixed to only require a forward iterator.
