c_mark_addressable is meant to be called during parsing.  It may affect 
the IL that will be generated, so you can't expect to be able to call it 
during optimization.

You haven't given us a copy of your patch, or the C code for your 
testcase.  It is difficult to say much definitive when we are lacking 
detailed info about what you are doing.
