While it is acceptible that the Frama-C value analysis doesn't support all esoteric gcc contructs (like __attribute__), issueing a warning that "alignied(0)" isn't supported would help the user to understand the reasons for the warning. ## Attachments - [aaa.c](/uploads/da286bc72aa9f2a0fbb3e13ad293ea02/aaa.c) - [aaa2.c](/uploads/366b803f2d48dc409aec4d71a24cf3fb/aaa2.c)
