> Project: ActiveMQ C++ Client

> Affects Versions: 2.0
> Reporter: Albert Strasheim
> Assigned To: Nathan Mittler
> Priority: Minor
> Fix For: 2.0

> 
> 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.
