Hi Valdas, thanks for helping out.
I didn't make clear - this crash is happening at connect time, I'm never 
actually able to establish retrieve an ODBCConnection object back from 
the connection attempt, so I'm pretty sure it's unrelated to cursors in 
the DB. To double-check that sort of thing I'm running a dedicated test 
database on an otherwise unused box, and I've tried stopping the 
database completely and restarting it before loading the Squeak image 
and attempting a connection. Result: Squeak still crashes. I'm positive 
that the C in the Intersystems' ODBC driver is tramping on Squeak somehow.
