Quantum Espresso (http://www.quantum-espresso.org/download.php) is miscompiled,
cf. http://www.democritos.it/pipermail/pw_forum/2010-March/016356.html
Fetch code, configure with F77=gfortran F90=gfortran and compile. Run the
example02 and compare the output for "ph.x < si.dynG" with the reference, with
an other compiler or with gfortran 4.3. Compare e.g. the "Dielectric constant"
matrix. The error is about 10%; for the "Effective charges" it is even larger.
I am currently hunting the regression and then will try to reduce the code.
