Dear Irwandi,

Thank you for the report and the proposed fix. I have entered your report into the sac issue tracker. The project only has volunteer developers so I am not sure when it will be evaluated. It is very helpful that you have identified a potential fix.

I am CC'ing the sac-help mailing list as this information may be useful for others as well. For future reference I recommend sending such questions directly to the list:

Thank you again for reporting this.

regards,

Dear all;

I have fix the problem, in the program xmerge.c at line 341, I make this change
// y[i] = yb + i *(ye-yb)/(e-b); //old
y[i] = yb + (i-b) *(ye-yb)/(e-b); //new
I hope you can update the program to repair the bug.

I am looking forward you email for this update.

Best regards,
