Issue to compile in VS 2008, VC 9.0.30729.1 SP without Microsoft extensions

[Dr. Sergey Kiselev <SergK13@…>]

The issue appears first in 1.35.0 version. The version 1.34.1 is still OK. It is only appears when microsoft extentions are disabled. The library is "Iterator". For version 1.35.1: the file is iterator_concepts.hpp, line nuber is 136:

BOOST_concept(SinglePassIterator, (Iterator))
    : IncrementableIterator <Iterator>
    , boost::EqualityComparable <Iterator>

  {
--->>>      BOOST_CONCEPT_ASSERT((
          boost::Convertible<
             BOOST_DEDUCED_TYPENAME SinglePassIterator::traversal_category
           , boost::single_pass_traversal_tag
          > ));
  };

The first line of error message is \boost\include\boost-1_35_0\boost/iterator/iterator_concepts.hpp(136) : error C2146: syntax error : missing ',' before identifier 'traversal_category'

IMO this is almost certainly a compiler bug, but for us to be sure it would help if you could post the preprocessor output.

PreprocessorOutput (stripped)

[SergK13Stuff@…]

I have posted preprocessor output which has been generated on boost version 1.35.0 and 9.0.30729.1 SP .NET 3.5 SP1 without Microsoft extensions. I have changed the flag in settings: C/C++/Preprocessor/Generate Preprocessor File to "With Line Numbers (/P)" in order to produce this file. After that file has been stripped off all information which is irrelevant I think. I just leave what is connected to the problem. However when I enable this flag my cpp files is compiled without any errors. Do you have any suggestions?

[Dr. Sergey Kiselev <SergK13@…>]

The same error with Visual Studio 2010 (10.0.40219.1 SP1Rel) .NET (4.0.30319 SP1Rel)! I have tested it with 1.47.0 boost, but this bug should be started from 1.35.0.

Dave,

I have posted additional information and preprocessor output. Any estimates when is it going to be fixed?

[Dave Abrahams]

No estimate, sorry. It seems highly unlikely that this problem has anything to do with Boost code, as there are no compiler-specific implementation details in BOOST_CONCEPT_ASSERT, so I can't give a very high priority to looking at this.
