Im connecting to SQLServer using the above, using unixODBC-2.3.1.  My test program works fine, my main application fails after successfully connecting to the database when it calls SQLGETDIAGRECW on line 4447 of __info.c.  mky stack looks is below, and the arguments to SQLGETDIAGRECW are

SQLGETDIAGRECW(connection=0x00000000006c19c0,
           head->handle_type = 2,
           handle=0x000000000070e650,
rec_number=1,
sqlstate={31152,65535,2,0,94,0},
&native (native=0),
msg1=0x0000fffffff74c0 (byte 0 = NULL)
sizeof(msg1),
&len (len=260545));

My test program has similar arguments, except sqlState={31856,99,0,0,75,0} and works fine.  Any ideas folks?

Program received signal SIGSEGV, Segmentation fault.
