Either your compiler is buggy, or it requires some specific options
to run a relatively large code like PWscf. If you paid real money
for the PGI compiler, complain with the vendor. In the meantime,
try a recent version of gfortran or a non-buggy version of the Intel
compiler (latest v.11 should be ok)
