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]
