Hello! I'm trying to build boost-1.40.0 and have problems with Boost::Test. Please take a look at build log: ------------------------------------------------------------------------ common.mkdir /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test common.mkdir /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4 common.mkdir /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4/debug gcc.compile.c++ /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4/debug/const_string_test.o gcc.link /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4/debug/const_string_test testing.capture-output /home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4/debug/const_string_test.run ====== BEGIN OUTPUT ====== Running 6 test cases... ../../libs/test/example/const_string_test.cpp(71): error in "data_access_test": exception std::out_of_range is expected *** 1 failure detected in test suite "const_string test" EXIT STATUS: 201 ====== END OUTPUT ====== LD_LIBRARY_PATH="/usr/local/bin:/usr/local/lib:/usr/local/lib32:/usr/local/lib64:$LD_LIBRARY_PATH" export LD_LIBRARY_PATH "/home/krivenok/dev_builds/boost_1_40_0_build/boost/bin.v2/libs/test/example/const_string_test.test/gcc-4.4/debug/const_string_test"

However, common_layer::const_string doesn't provide such validation. operator[] and at() are identical in const_string: char operator[]( size_t index ) const { return m_begin[index]; } char at( size_t index ) const { return m_begin[index]; } I commented BOOST_CHECK_THROW out and now Boost::Test compiles w/o any errors. I think implementation of const_string::at() should be fixed.
