[Frama-c-discuss] problem with matrix pointer

  • Subject: [Frama-c-discuss] problem with matrix pointer

Hi all,
Here is an example  simple_2.c
I am facing with the following issue :

float  *foo(float (*C)[2][2],float (*x)[2]){
 float (*matrix_C)[2][2] = C;
 float (*vector_x)[2] = x;
 float foo_var=0;
 int i=0, j=0;
 foo_var =(*vector_x)[j];
 //foo_var =(*matrix_C)[i][j];
 return (*x);
};

If foo_var = (*vector_x)[j]; then there is no problem with the command :
frama-c -jessie -wp-prover why3ide simple_2.c

However, if foo_var =(*matrix_C)[i][j]; I am getting the following error:
failure: typeOfLval: Mem on a non-pointer ((*matrix_C)[i])

I am fairly sure I missed something in the frama-c or jessie documentation.
Can somebody help me with this issue ?
