I currently have the Planck Likelihood Code installed with gfortran and CosmoMC compiled with gfortran. I had not had this issue when I used ifort. Due to an issue with the PLC, it had to be reinstalled, however, and it was reinstalled with gfortran.
Here are two samples of the last things written to the screen by CosmoMC:
