I eventually kind of workaround this issue by merge `Requestor` and `Streamer` classes into a single one. I guess two existing instances of these classes may conflict with each other.
@syswizard We're a bit behind but making good progress. Our first beta release should go live within 1-2 weeks. You can request to be added to our notification list if you email support at activetick.com.

I can confirm that, without modify the source code, the compiled binary is working without such issue in linux system. So the error comes from the shared library `libActiveTickServerAPI.dylib` for Mac OS X system. My guess would be that the `atfeed-cppsdk-osx.i386.tar.gz` SDK is casting memory errors under 64-bit Mac System.
