Not able to print correct line numbers for then part of if statement,

Hi,

I am playing around a bit of with clang and have hit a problem. For a Clang input with if statement, I am trying to obtain line number of beginning of Then statement and then print it out. But I am not able to make sense of the output. Can you please help. In a nutshell I am trying to get presumed loc from sourceloc of Then statement. For the following input, its printing 6 and 12 instead of 4 and 8.

1 #include <stdio.h>

2 int func (int abc, int xyz) {

3     if (abc-1)
4     {
5         printf ("1\n");
6     }

7      if (abc-2)
8     {
9         printf ("2\n");

10 }

11

12 return 0;

13 }
