Hi,

   I am trying to lift a code for x86 architecture and later run it on Klee-2.1.
So that, Klee analysis it and gives which type of error is it. But it is not
giving that error which is expected.
For example, here written a code for free.err but when we try to lift it and
analysis it with Klee it gives me out bound error i.e ptr.err.
 Could you help in this problem or give me any examples for that. Here the code
,



#include <stdlib.h>

   int global[3];
   int main(void)
             {
                    free(global); // free.err
                    break;
               }

Thanks in advance...


Best,
Mohit
