execution_monitor.ipp causes compilation failure

[chris.cooper@…]

test\impl\execution_monitor.ipp causes compilation failures from MSVC 10.0 because of this function:

int BOOST_TEST_CALL_DECL
assert_reporting_function( int reportType, char* userMessage, int* )
{
    switch( reportType ) {
    case BOOST_TEST_CRT_ASSERT:
        detail::report_error( execution_exception::user_error, userMessage );

        return 1; // return value and retVal are not important since we never reach this line
    case BOOST_TEST_CRT_ERROR:
        detail::report_error( execution_exception::system_error, userMessage );

        return 1; // return value and retVal are not important since we never reach this line
    default:
        return 0; // use usual reporting method
    }
} // assert_reporting_function

The MSVC compiler gives a warning that there is unreachable code (the lines that say "return 1;") and then because it has been told to treat warnings as errors, the compilation fails.

Hi,

Why would MSVC treat warnings as errors?
