Hi Adam,

If you check the include chain you will notice that Bimap is including
boost/mpl/lambda.hpp through the lib dependencies.

Your example can be reduced to this:

  #define BOOST_MPL_CFG_NO_PREPROCESSED_HEADERS
  #define BOOST_MPL_LIMIT_METAFUNCTION_ARITY 9

  #include <boost/mpl/lambda.hpp>

  int main() {
      return 0;
  }

That fails for me with GCC 4.7.2 and Boost 1.52.

It seems that you are hitting the compiler limits. It works if you use
8 as the limit. You can open a ticket in Trac for MPL devs to look
into the issue.

Best regards
Matias
