Outliner does not outline pointer arithmetic expressions correctly

[tiagolascasas]

E.g., in CortexSuite PCA, this is generated:

void vector_out0(float *decomp_0, float *v) {
   decomp_0 = v - 1;
}

void vector(int n, float **rtr_val) {
   float *v;
   float *decomp_0;
   v = (float *) malloc((unsigned int) n * sizeof(float));
   if(!v) {
      erhand("Allocation failure in vector().");
   }
   vector_out0(decomp_0, v);
   *rtr_val = decomp_0;
   
   return;
}

whereas the correct version should be:

void vector_out0(float **decomp_0, float *v) {
   *decomp_0 = v - 1;
}

void vector(int n, float **rtr_val) {
   float *v;
   float *decomp_0;
   v = (float *) malloc((unsigned int) n * sizeof(float));
   if(!v) {
      erhand("Allocation failure in vector().");
   }
   vector_out0(&decomp_0, v);
   *rtr_val = decomp_0;
   
   return;
}
