Environment

NetWare 6.5
TSATEST.NLM Version 1.19.00 27 October 2004
TSATEST.NLM Version 1.19.01 07 November 2005
TSANDS.NLM
Novell NetWare 6.5 Support Pack 5
Novell NetWare 6.5 Support Pack 4

Situation

eDirectory backup test..

These versions of TSATEST are in NW65SP4a and NW65SP5UPD1 respectively, and make a call to TSANDS.NLM (which older versions do not) which results in an abend in the LIBC string copy routine.

This abend only occurs when TSANDS is loaded and then TSATEST is run with the switch /v=NDS. In that situation it occurs every time.
