In some cases (presumably when a database contains more attributes than defined in the scheme) a heap error may be detected at stop of slapd.

Below is the result of attempts to find a bug(s) with Valgrind. It is enough to corrupt a malloc's heap!

Please provide a test case. Unable to reproduce this on a local database with commented out schema. I get:
