Page fault on connection

am 14.06.2006 19:27:30 von Andrus

I'm using Microsoft Visual FoxPro 9 SP1 in Windows 98
This problem occurs both in last stable release and in development snapshot
of ODBC driver.

In one computer, VFP SQLSTRINGCONNECT() call

causes Windows error

MYAPP caused an invalid page fault in module KERNEL32.DLL at 0167:bff7a379

This occurs always in one Win 98 computer while connnecting to one server.
Connecting to other server using same exe in this computer works OK
This occurs if I supply wrong or bad password to server.

Driver log when error occurs (ip addresses changed)
