I had a couple of seg. faults when resync'ing my servers after upgrading to the upcoming 2.4.16 release. Looks as if a copy of the backend must be used when testing the filter in syncprov_matchops. See the gdb output at the end. Note, some function names are incorrect due to optimization. A fix is coming.
