-----------------------------------------
Actually looking at where this crashes turns up something interesting. The
stack looks like this:
ntdll.dll!7c901230()
[Frames below may be incorrect and/or missing, no symbols loaded for ntdll.dll]
ntdll.dll!7c96c943()

The code that crashes is this:
{noformat}
if( textMessage != NULL ) {
text = textMessage->getText();
} else {
text = "NOT A TEXTMESSAGE!";
}
{noformat}
It crashes where the destructor for text is called, because it's trying to
deallocate the string from the wrong heap. This doesn't make complete sense to
me yet, but it doesn't look good for the mixing of runtimes.

> Key: AMQCPP-118
> URL: https://issues.apache.org/activemq/browse/AMQCPP-118
> Project: ActiveMQ C++ Client
> Issue Type: Improvement
> Reporter: Albert Strasheim
> Assignee: Nathan Mittler
> Fix For: 2.1
>
>
> Cross-runtime allocation and deallocation can cause problems on Windows (and
> maybe other platforms) where you can have code linked against more than one
> runtime in the same program. There should be a way to be sure that you
> allocate and deallocate AMQCPP objects using code linked against the same
> runtime (i.e. allocate and deallocate from the same heap).
