Hey Jessica - The SIGBUS you are receiving indicates that there is likely some funniness happening with memory addressing / access somewhere. Especially since your test flowgraph is so simple, using GDB to get a backtrace might point you to the offending code pretty quickly. For more details on how to do this, check out this page on our Wiki: https://wiki.gnuradio.org/index.php/TutorialsDebugging#Expert_debugging_tools
Have you tried this already? If so, can you share the backtrace?
