Timothy Bish commented on AMQCPP-304:
-------------------------------------
Why would you link to the AMQCPP code and then not use it?
> SEGFAULT on shutdown
> --------------------
>
> Key: AMQCPP-304
> URL: https://issues.apache.org/activemq/browse/AMQCPP-304
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: CMS Impl
> Affects Versions: 3.2.1
> Environment: Linux
> Reporter: Kevin Quick
> Assignee: Timothy Bish

> If application does not initialize (or use) ActiveMQ-CPP before exiting, global static elements will call apr functionality without initialization of same, resulting in a segfault.
> Similar issue to AMQCPP-303. This global static element is:
> activemq/commands/ActiveMQDestination.cpp:
> ...
> util::ActiveMQProperties options;
> Test file (mqtest.cpp):
> #include <iostream>
> // Normally comes from library include: explicit here facilitate problem demonstration
> #include <activemq/commands/ActiveMQDestination.cpp>
> int main(int, char**)
> {
> std::cout << "Hello" << std::endl;
> }
> To reproduce:
> $ gdb mqtest
> ...
> (gdb) r
> Starting program: /Mount/Work/per_mbus/persephone_trunk/pjs/nexus_handlers/mbus/mqtest
> [Thread debugging using libthread_db enabled]
> Hello
> Program received signal SIGSEGV, Segmentation fault.
