I realized I should add some more information, since that core file was
generated with a different binary than the one you will be using. Here's
the backtrace and some print commands that show that the problem is that
we're attempting to dereference state->base while it is null.

Core was generated by `sss_useradd tempuser'.
Program terminated with signal 11, Segmentation fault.
