Summary

0001005: defining two axioms with same name causes kernel crash

Description

Running "frama-c -cpp-command 'gcc -C -E -I.' -jessie '-jessie-why-opt=-exp goal' -no-unicode -jessie-atp simplify list.c" under why 2.30 on the attached program caused a kernel crash, asking to report it here. The last output was:

[kernel] failure: trying to register twice property `axiom
                  inj1'.
                  That is forbidden (kernel invariant broken).
[kernel] The full backtrace is:
         Raised at file "src/kernel/log.ml", line 509, characters 30-31
         Called from file "src/kernel/log.ml", line 503, characters 9-16
         Re-raised at file "src/kernel/log.ml", line 506, characters 15-16

         Called from file "src/kernel/cmdline.ml", line 200, characters 4-8

         Frama-C aborted because of internal error.
         Please report as 'crash' at http://bts.frama-c.com/.

The program "list.c" is obviously faulty, as it defines two axioms with the same name "inj1".
