Could you try to use -- as a baseline -- the GNU compiler that comes on your RedHat (or Centos) 6 box (out of /usr/bin)?
Have you already try to use this option and found problem with it?

Brilliant! Using the system compiler (gfortran 4.4.7) and an older version of the mpich2 libraries (I did not have the openmpi libraries for the older compiler readily available) everything went smoothly. However, this issue left me puzzled as to the functionality of the 4.9.2 compilers. Given that these are supposedly heavily utilized, I am surprised that this problem did not reveal itself previously. Anyway, thank you very much!
