afaics the problem is in the BOOST_MPL_ASSERT_MSG invocation. the last parameter T leads to an abstract type instantitation.

This problem had already been fixed in trunk, but the fix didn't make it into the release branch in time for 1.35. I have merged the fix into the release branch in case there is a 1.35.1 release.

If you would like to make the change locally, the simple fix is to change this:

    BOOST_MPL_ASSERT_MSG( (!is_char_array<T>::value), IS_THIS_AN_ARRAY_OR_A_NULL_TERMINATED_STRING, (T) );

to this:

    BOOST_MPL_ASSERT_MSG( (!is_char_array<T>::value), IS_THIS_AN_ARRAY_OR_A_NULL_TERMINATED_STRING, (T&) );

Note the (T&) at the end, rather than the (T).
