         Unexpected error (Not_found).
         Please report as 'crash' at http://bts.frama-c.com/. [^]
         Your Frama-C version is Phosphorus-20170501-beta1.


The problem disappears if:
* the source file order is exchanged on the command line,
* the overloaded predicate 'Bnd(integer n)' in while.c:5 is renamed e.g. to 'Bnd2',
* the trivial 'ensures' clause is removed in whole.c:10, or
* the 'requires' clause in whole.c:9 is changed to 'Bnd(1,(int)0)', i.e. 'Bnd' is inlined.
TagsNo tags attached.

Note that the contents of 'part.c' is a proper prefix of that of 'whole.c' (except for the closing '*/'). The crash problem also disappears when a definition disagrees between both files.

I looked at another example and it really looks like Frama-C has a problem with overloaded predicates
when multiple files are processed.
