[Frama-c-discuss] Plug-in Jessie

Test of the tutorial Jessie : 2.1)Memory safety on frama-c , Nitrogen, plug-in Jessie(I have not the GUI Jessie) :

#pragma JessieIntegerModel(math)
#pragma JessieTerminationPolicy(user)
int binary_search(long t[], int n, long v) {
int l = 0, u = n-1;
while (l <= u) {
int m = (l + u) / 2;
if (t[m] < v)
l = m + 1;
else if (t[m] > v)
u = m - 1;
else return m;
}
return -1;
}


After this test, the following information appear:

[jessie] Starting Jessie translation

[jessie] user error: Jessie subprocess failed:   jessie  -why3ml  -v       -locs Jessie_2.cloc Jessie_2.jc

But we have not information about the memory safety, what can I do to have information about memory safety?
