Full_Name: Leonid Yuriev Version: 2.4-HEAD OS: RHEL7 URL: ftp://ftp.openldap.org/incoming/ Submission from: (NULL) (31.130.36.33)

I have previously reported on the two SIGSEGV backtraces (see a copy below). This bug was reproduced again during our replication test. I think that now I have found the reason - the PS_FIX_FILTER flag not cleared after update the filter.

Patch will be available shortly. Please review and merge.

Leonid.
