Dear all, I am running Frama-C Beryllium-20090902 with Why 2.21. I can successfully run "frama-c -jessie no_failure.c" on the below no_failure.c file : //@ predicate P0{L}(int t[], int i) = t[i]==1; /*@ axiomatic No_Failure_1 { predicate P1{L}(int t[], int i); axiom aP1{L} : \forall int t[], int i; i==0 && P0{L}(t,i) ==> P1{L}(t,i); }*/ /*@ axiomatic No_Failure_2 { predicate P2{L}(int t[], int i); axiom aP2{L} : \forall int t[], int i; i!=1 && !P0{L}(t,i) ==> P2{L}(t,i); }*/ But then, I if decide to merge the definitions of predicates P1 and P2 into a single axiomatic, I get the following failure.c file : //@ predicate P0{L}(int t[], int i) = t[i]==1; /*@ axiomatic Failure_Unexpected_internal_region_in_logic { predicate P1{L}(int t[], int i); predicate P2{L}(int t[], int i); axiom aP1{L} : \forall int t[], int i; i==0 && P0{L}(t,i) ==> P1{L}(t,i); axiom aP2{L} : \forall int t[], int i; i!=1 && !P0{L}(t,i) ==> P2{L}(t,i); }*/ If I then run "frama-c -jessie failure.c", I get the below error : Uncaught exception: Failure("Unexpected internal region in logic") Could you please explain me why? -- Thank you in advance for your help, David The information in this e-mail is confidential.
