| Summary | 0002147: Frama-C problem with macro substitution in annotations |
| Description | This piece of code should parse with frama-c, but does not:
#define MACRO 3
void m() {
char buf[MACRO+1];
//@ assert \valid(buf+(0..MACRO));
}
Upon execution, frama-c gives back "[kernel] user error: unbound logic variable MACRO in annotation.".
This piece of code, however, executes as it should:
#define MACRO 3
void m() {
char buf[MACRO+1];
//@ assert \valid(buf+(0.. MACRO));
}
This code is also okay:
#define MACRO 3
void m() {
char buf[MACRO+1];
//@ assert \valid(buf+(0..(MACRO)));
}
It seems that frama-c refuses to substitute defines directly after a .. operator. |
