release crashes debug does not   

When I build with Release my program crashes.
When I build with Debug it does not!  Aack!

FWIW, the error report file contains

RE: release crashes debug does not   

One of the possible causes is that you have one or more uninitialised 
variables somewhere. When building in debug, variables are initialised by the 
environment automatically. When building in release mode this is not done, so 
they can be set to whatever happens to be there.
