Description :
When using arr[0] == 1 in annotation where arr is array with initialization like this: arr[] = {1, 2, 3}, Jessie does not see information about initialization, resulting in unprovable formula.
Additional Information :
Starting from the following file:
//@ ensures \result = 1; int init_array() { int arr[] = {1, 2, 3}; //assert arr[0] == 1; //forall integer i; 0 <= i < 3 ==> arr[i] < 4;
return arr[0]; }
frama-c -jessie file.i
produces a correct file.jessie/file.jc but an incorrect file.jessie/why/file.why (assert doesn't work).
