slapd will crash if a database has the audit overlay enabled and the attribute
jpegPhoto will be modified or added with data bigger than ~27KB.

`/usr/local/libexec/slapd': free(): invalid next size (normal)

Verified with custom builds on Ubuntu lts 12.04/14.04/Mint 14 and bdb/mdb.

Remove the audit overlay or migrate back to 2.4.39 solves the problem.
