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/logic/property_status.ml", line 349, characters 4-132 Called from file "list.ml", line 69, characters 12-15 Called from file "list.ml", line 69, characters 12-15 Called from file "src/kernel/file.ml", line 1196, characters 5-43 Called from file "src/kernel/file.ml", line 1412, characters 4-27 Called from file "src/kernel/ast.ml", line 64, characters 2-28 Called from file "src/project/state_builder.ml", line 490, characters 17-21 Called from file "src/kernel/boot.ml", line 33, characters 60-72 Called from file "src/kernel/cmdline.ml", line 723, characters 2-9 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".
