> In my debugging to figure out what's going on with AMQCPP-59, I'm sometimes seeing invalid
stuff getting printed out when I do printStackTrace on some exceptions. I think this might
be because CMSException::what returns getMessage().c_str(), i.e. it seems to be returning
the c_str of a std::string that is allocated on the stack, since getMessage returns std::string.
> An example of where what() is being called that seems to be causing problems is on line
84 of ActiveMQConsumer.cpp. When I catch this exception later on and print its stack trace
or call its getMessage, I get garbage.
