Description :

When running Frama-C / WP with -wp-qed-checks option, most of generated ALt-Ergo files are truncated and thus invalid.

For example, on following file: """ /*@ requires 0 <= x <= 10; ensures 1 <= \result <= 11; */ int f(int x) { return x + 1; } """

and calling Frama-C with: frama-c -wp-out out -wp -wp-qed-checks f_wp.c

Here is one of generated files: """ $ cat out/typed/Qed_19_20.ergo (* ---------------------------------------------------------- ) ( --- Qed-19-20 --- ) ( ---------------------------------------------------------- *)

goal Qed_19_20: (0 < """

Best regards, david

Steps To Reproduce :

$ cat > f_wp.c /*@ requires 0 <= x <= 10; ensures 1 <= \result <= 11; */ int f(int x) { return x + 1; } ^D

$ frama-c -wp-out out -wp -wp-qed-checks f_wp.c

$ cat out/typed/Qed_19_20.ergo
