Exception when using DLL Matlab with Visual C++ 8.0

USING DLL Matalb with Visual C++ 8.0

I am using an *.m file to generate a dll. The m code is simple like y=2x. Then the DLL is linked in Visual C++ 8.0. For the moment, the result seems right when i run exe, but i've got a lot of exception on output window :

Exception Microsoft C++ : xsd_binder::MalformedDocumentError
Exception Microsoft C++ : fl::i18n::MwLcDataNotFound
Exception Microsoft C++ : boost::thread_interrupted
Exception Microsoft C++ : CryptoPP::AES_PHM_Decryption::InvalidCiphertextOrKey
Exception Microsoft C++ : tfFailedException
Exception Microsoft C++ : jitCgFailedException
Exception Microsoft C++ : varflowFailedException
Exception Microsoft C++ : tfFailedException
Exception Microsoft C++ : tfFailedExceptionNoUCB

Environment is windows XP / VC++8.0 / matlab7.1

Could you explain me ?

Thanks

David - please indicate how you have created the DLL and how you are using it within your C++ code.
