Here's the bit from the backtrace that's relevant:
>   2 0x0cf429b4 test_data_msg_update+0x5b1() [dlls/crypt32/tests/msg.c:445] in
> crypt32_test (0x7f21fd08)

Here are the lines leading up to line 445 of tests/msg.c.  Notice the comments
:)
        /* Calling update after opening with an empty stream info (with a bogus
         * output function) yields an error:
         */
        /* Crashes on some Win9x */
        msg = CryptMsgOpenToEncode(PKCS_7_ASN_ENCODING, 0, CMSG_DATA, NULL,
NULL,
         &streamInfo);
        SetLastError(0xdeadbeef);
        ret = CryptMsgUpdate(msg, msgData, sizeof(msgData), FALSE);

This is indeed a valgrind bug, the exception is supposed to be caught.
