> 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]
