The tests were run with this compiler:

Compaq C++ V6.5-031 for Compaq Tru64 UNIX V5.1 (Rev. 732)

With the latest cvs I am getting the exact same results as Markus even though
my compiler is a slightly older version. Gennadiy's fixes appear to have done
something good.

The internal compiler error is triggered by this construct in
unit_test_suite.cpp:

            BOOST_UT_LOG_BEGIN( BOOST_TEST_STRING_LITERAL( __FILE__ ),
__LINE__,
 log_fatal_errors )
                "Test case initialization has failed"
            BOOST_UT_LOG_END;

Using the preprocessed file, this doesn't compile:

            boost::unit_test::unit_test_log::instance()
            << boost::unit_test::begin()
            << boost::unit_test::level( log_fatal_errors )
            << boost::unit_test::file((boost::unit_test::literal_string(
"junk.c
pp", sizeof( "junk.cpp" ) - 1)))
            << boost::unit_test::line( 127 )
            << "Test case initialization has failed"
            << boost::unit_test::end();;

But this does:

            boost::unit_test::literal_string lit_str(
              "junk.cpp", sizeof( "junk.cpp" )-1);
            boost::unit_test::unit_test_log::instance()
            << boost::unit_test::begin()
            << boost::unit_test::level( log_fatal_errors )
            << boost::unit_test::file(lit_str)
            //<< boost::unit_test::file((boost::unit_test::literal_string(
"junk.c
pp", sizeof( "junk.cpp" ) - 1)))
            << boost::unit_test::line( 127 )
            << "Test case initialization has failed"
            << boost::unit_test::end();;

I.e. the ICE could be avoided by changing the BOOST_UT_LOG_BEGIN macro.
Gennadiy, email me if you are interested in getting access to our machine in
order to fix this problem.
