Brian McKinnon commented on AMQCPP-326:
---------------------------------------

This issue is actually much larger than I originally thought.  It may be easier for me to stop the C4 memory manager than to make all the changes to activemq-cpp to ensure that the library is safe across memory managers.  You can choose to ignore this request... unless you are interested in me spending more time to try and resolve this issue.

> The C4 game engine has recently implemented there own memory management module overloading the new and delete operations.  As a result the std::string returned by cms::Topic::getTopicName causes the system to crash.   The custom memory manager renders the simple solution of including the same msvc runtime dll unusable. A solution would be to implement a void cms::Topic::getTopicName(std::string & name) function instead or in addition to the existing function.
