     Frama-C aborted because of internal error.
     Please report as 'crash' at http://bts.frama-c.com/.
     Your Frama-C version is Nitrogen-20111001+dev.
     Note that a version and a backtrace alone often does not have information
     to understand the bug. Guidelines for reporting bugs are at:

Additional Information :

I think it would be ok just to be stricter for multiple incompatible declarations.
