<div>Thanks for your reply, Dave. I was using 1.2.1p1 version. I do not understand the fix. Could you give me more hints on this?</div>

I was trying to locate this file helper_fns.c. And I found this file name appeared in libmpich.a under MPI lib folder. This is the only clue I have found. But I do not know what is wrong with it. I hope to get some advice here. Thank you very much.<br>
