This is the backtrace for the failed spectral_mi bloom filter test on my operating system (Ubuntu 12.04). Let me know if you need any more information.

Thanks for reporting the bug. It does not occur on Darwin and will test it on a Linux.

I'm closing this issue after the recent rewrite of the library. If it still persists, please reopen it.
