[Pw_forum] iotk error - again

[Lorenzo Paulatto]

Are you using the most recent version of intel fortran compiler (it's  
called XE, or 11.0)? It has a lot of problem, we've been discussing the  
issue some time ago: it definitely is a miscompilation problem. I have a  
stinky workaround, but the best solution is to downgrade the compiler.

cheers
