First: what version? Help->About tells.

The major thing to watch out for is timing dependent sequence, e.g. 
timing loops, or this sequence must occur in X cycles etc. types of 
code. In either case, you can disable the code compressor on relevant 
code fragments.

Increase the HW stack by 10 bytes or so. Hopefully this will not put 
pressure on your software stack.

Otherwise, the code compressor has been stable and robust for a 
number of years now.
