False positive in alias analyze of cpair

[Jason2031]

Hi jakkdu. It seems like apisan doesn't support alias analyze of cpair checker. Consider the following code:

#include <stdio.h>
void good1(){
  int* a=(int*)malloc(sizeof(int));
  // do something...
  free(a);
}
// other similar malloc-free pattern omitted...
void goodx(){
  int* a=(int*)malloc(sizeof(int));
  int* b=a;
  // do something...
  free(b);
}

Apisan makes complaints that malloc-free pattern in goodx is a potential bug.

Sorry, Jason.
I was too busy.
I just checked the cpair one.
Could you give me the full code that you test?
I think goodx seems not considered as potential bug.
Thanks.
