>                 URL: https://issues.apache.org/jira/browse/AMQCPP-533
>             Project: ActiveMQ C++ Client
>          Issue Type: Bug
>          Components: Stomp
>    Affects Versions: 3.8.1
>         Environment: CentOS 6
>            Reporter: Vince Hurrell
>            Assignee: Timothy Bish
>             Fix For: 3.8.3, 3.9.0

> Here is the afflicted code:
>     try {
>         Pointer<ActiveMQBytesMessage> bytesMessage = message.dynamicCast<ActiveMQBytesMessage>();
>         frame->setBody(bytesMessage->getBodyBytes(), bytesMessage->getBodyLength());
>         frame->setProperty(StompCommandConstants::HEADER_CONTENTLENGTH, Long::toString(bytesMessage->getBodyLength()));
>         return frame;
>     } catch (ClassCastException& ex) {
>     }
> The return from getBodyBytes is passed to the frame, which then accepts the contents of the buffer and copies it into a vector.  As the documentation for getBodyBytes indicates, freeing of the data returned by the function is the responsibility of the caller.
