| Summary | 0000885: Typing error on expression array == pointer | ||||||||
| Description | File: extern int t1[10]; //@ requires t1 == \null; void main(void) { ; } is interpreted as: extern int t1[10]; //@ requires (int *)t1 == (int []) \null; void main(void) { ; } Both operands of the equality have not the same type! | ||||||||

I think that t1 expression cannot be implicitly casted into a pointer (from ACSL reference manual). I don't remember if implicit cast from pointer to array are allowed. If it is not the case, the equality t1 == \null should be rejected by Frama-C. |
