Hi
Background: 1_33_1
Example : boost_1_33_1\libs\serialization\vc6ide\test_no_rtti
I can run the example successfully on Debug mode with no warning and no
error.
However, it has several warnings, abnormal operation and memory leak when
running on release mode.
The following is the warnings:
d:\barr\serialization\boost\boost_1_33_1_bk\boost\smart_cast.hpp(200):
warning C4541: 'dynamic_cast' used on polymorphic type 'polymorphic_base'
with /GR-; unpredictable behavior may result
d:\barr\serialization\boost\boost_1_33_1_bk\boost\smart_cast.hpp(200):

]
..\..\..\boost\serialization\void_cast.hpp(191) : see reference to

..\..\..\boost\serialization\base_object.hpp(103) : while compiling
class
d:\barr\serialization\boost\boost_1_33_1_bk\boost\serialization\extended_type_info_typeid.hpp(92):
warning C4541: 'typeid' used on polymorphic type 'polymorphic_derived2' with
/GR-; unpredictable behavior may result
Then the following is the console output after invoking the release exe
file:
Running 1 test case...
unknown location(0): fatal error in "test_main_caller( argc, argv )":
std::bad_typeid: Bad read pointer - no RTTI data!
*** errors detected in test suite "Test Program"; see standard output for
details
Detected memory leaks!
Dumping objects ->
{263} normal block at 0x00983EA8, 4 bytes long.
Data: <D E > 44 D1 45 00
Object dump complete.
What should I do to make the release mode run correctly?
Best regards
Barr Ng
