Major Description
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
