In my configuration slapd segfaults within a few hours repeatably when a NULL value is somehow passed as a filter to test_filter in the syncprov overlay.

I'm running "threads 64" as I have 62 consumers connecting and this was required to prevent unrelated searches from timing out when all the consumers connect at once.

Program received signal SIGSEGV, Segmentation fault.
