SE 2.2 beta #2 code generation

Hi all,

Can anyone suggest what features of Eiffel code might compile differently 
between SE 2.1 and SE 2.2 beta #2 ?

My Eiffel project, which now compiles under both SE 2.1 and SE 2.2 beta 2, 
behaves incorrectly when compiled with SE 2.2.

The symptoms suggest that it may be a change in semantics of either bit 
manipulation, or integer calculation.

Any suggestions welcome, including pointers to areas of SE source code that 
have changed in regard to C code generated for INTEGER_xx etc.
