krb5_mcc_start_seq_get() is in the traceback, so the memory cache change is a clear candidate for the bug. I can't find anything wrong with the code, though. From the stack trace, there appears to be a memory ccache on the list with an invalid mutex, but I don't see any way of getting into that state.
