572649 - DS8.2 crashes on RHEL 4 (corresponding to bob, ber_2 test case)
https://bugzilla.redhat.com/show_bug.cgi?id=572649
Fix Description: There was a chance to jump to error_return before
back_txn structure was initialized. In the error handling, the
transaction abort is called against the garbage address. Slapi_DN
also gets freed without an initialization. Now these variables
are initialized first.
