Subject Segfault with ActiveMQ-CPP 3.4.0
Date Tue, 09 Aug 2011 15:38:33 GMT
Hi everyone,

I've been using activemq-cpp 3.1.x for a while with success now.
But as it is getting more and more difficult to built it on modern platform
due to some old APR/APR-Util version, I thought it could be worth upgrading
my application to use the latest ActiveMQ-CPP 3.4 that use current
distributed APR version of the system (Mac and Linux).

I managed to compiled activemq-cpp 3.4 without any issue (no more complains
about incompatible APR version...).
Then I had to fix of the API to add the "throw()" that was missing to the
signature of the onMessage method and the destructor of the MessageListener.
Once this changed done, everything compiled. Although, as soon as the
application start, it segfault.

So I've tried with the your demo example available here
http://activemq.apache.org/cms/example.html
(I had to do the same "throw()" modifications)
And when I run it, I get the exact same segfault.

I'm running it on Mac OS X Lion
Here is the stack

Thanks for any help,

PS: I've attached a source directory that can be used with CMake to build
the code.
