Could you have given a code snippet to demonstrate it? I can't find any lexical_cast-related Date/Time failures in the Win32 regression test tables. Also, you may want to get the latest lexical_cast version from the CVS, as some problems were fixed after 1.30 shipped. However, in the test logs there are several errors for Comeau C++: lexical_cast_test / como-win32 Run output: Running 11 test cases... ..\libs\conversion\test\..\lexical_cast_test.cpp(73): error in "test_conversion_to_char": test '1' == lexical_cast<char>(1.0) failed [1 != 0] ..\libs\conversion\test\..\lexical_cast_test.cpp(97): error in "test_conversion_to_int": test 1 == lexical_cast<int>(1.0) failed [1 != 0] ..\libs\conversion\test\..\lexical_cast_test.cpp(99): error in "test_conversion_to_int": exception boost::bad_lexical_cast is expected ..\libs\conversion\test\..\lexical_cast_test.cpp(101): error in "test_conversion_to_int": exception boost::bad_lexical_cast is expected ..\libs\conversion\test\..\lexical_cast_test.cpp(124): error in "test_conversion_to_double": test 1.23 == lexical_cast<double>(1.23) failed [2061584302 != 3951034368] ..\libs\conversion\test\..\lexical_cast_test.cpp(125): error in "test_conversion_to_double": test std::numeric_limits<double>::max() / 2 ~= lexical_cast<double>(std::numeric_limits<double>::max() / 2) failed [4294967295 !~= 4292870144 (+/-0)] ..\libs\conversion\test\..\lexical_cast_test.cpp(149): error in "test_conversion_to_bool": test true == lexical_cast<bool>(1.0) failed [1 != 0] ..\libs\conversion\test\..\lexical_cast_test.cpp(172): error in "test_conversion_to_string": test "1.23" == lexical_cast<std::string>(1.23) failed [1.23 != 2061584302] ..\libs\conversion\test\..\lexical_cast_test.cpp(173): error in "test_conversion_to_string": test "1.111111111" == lexical_cast<std::string>(1.111111111) failed [1.111111111 != 1908373954] ..\libs\conversion\test\..\lexical_cast_test.cpp(213): error in "test_conversion_from_wchar_t": test 1.0 == lexical_cast<double>(L'1') failed [0 != 1] Exception in "test_conversion_from_wchar_t": std::bad_cast: bad lexical cast: source type value could not be interpreted as target ..\libs\conversion\test\..\lexical_cast_test.cpp(236): error in "test_conversion_to_wchar_t": test L'1' == lexical_cast<wchar_t>(1.0) failed [49 != 48] ..\libs\conversion\test\..\lexical_cast_test.cpp(277): error in "test_conversion_to_wstring": test L"1.23" == lexical_cast<std::wstring>(1.23) failed ..\libs\conversion\test\..\lexical_cast_test.cpp(278): error in "test_conversion_to_wstring": test L"1.111111111" == lexical_cast<std::wstring>(1.111111111) failed That's the only compiler reporting errors on the regression test, though. For example, I don't get any errors on Intel C++ 7.1 in strict mode. Does anyone have an idea of what could be wrong? What library/C back end is used for Comeau C++, here?
