In this test CW8 fails to do the operator lookup within the function scope. That is doing a "using namespace boost::assign" doesn't add the += operators to the resolution path for CW8. The workaround is to move the "using namespace" to the file scope: =================================================================== RCS file: /cvsroot/boost/boost/libs/assign/test/std.cpp,v retrieving revision 1.2 diff -u -r1.2 std.cpp --- std.cpp 21 Jul 2004 11:36:11 -0000 1.2 +++ std.cpp 24 Jul 2004 16:25:35 -0000 @@ -15,6 +15,7 @@ #include <string> using namespace std; +using namespace boost::assign; template< typename K, typename V > inline pair<K,V> P( K k, V v ) @@ -46,7 +47,6 @@ template< class C > void test_int_sequence() { - using namespace boost::assign; C c; BOOST_CHECK_EQUAL( c.size(), 0u ); @@ -59,7 +59,6 @@ template< class C > void test_string_sequence() { - using namespace boost::assign; C c; BOOST_CHECK_EQUAL( c.size(), 0u ); @@ -74,7 +73,6 @@ template< class C > void test_tuple_sequence() { - using namespace boost::assign; C c; BOOST_CHECK_EQUAL( c.size(), 0u ); @@ -88,7 +86,6 @@ template< class M > void test_map() { - using namespace boost::assign; M m; m += P( "january", 31 ), P( "february", 28 ), P( "march", 31 ), P( "april", 30 ), @@ -112,7 +109,6 @@ void test_tuple() { - using namespace boost::assign; vector<three> v_three; vector<four> v_four; vector<five> v_five; @@ -131,7 +127,6 @@ void check_std() { - using namespace boost::assign; test_int_sequence< deque<int> >(); test_int_sequence< list<int> >(); test_int_sequence< vector<int> >(); =================================================================== This make the test work on CW8, and still work on vc7.1 and mingw.
