confirmed.

I suspect it is due to the recent update of Gfortran from 4.5 to 4.7

We are not the first hit by such problem, see:

https://lists.fedoraproject.org/pipermail/packaging/2010-December/007530.html
http://fedoraproject.org/wiki/Packaging:Fortran

I will rebuild openmpi with GNU Fortran (GCC) 4.7.3
and see if that solve the issue

Marco
