CMSException::what returns c_str of temporary std::string
---------------------------------------------------------
Key: AMQCPP-61
URL: https://issues.apache.org/activemq/browse/AMQCPP-61
Project: ActiveMQ C++ Client
Issue Type: Bug
Components: CMS Impl
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.
