[Pw_forum] Error during phonon calculation

[Stefano de Gironcoli]

Strange errors, maybe also the one you encountered, may appear in 
parallel calculations if some
garbage is left in the outdir directory and is mis-interpreted by the 
phonon code (I dont know why
but will try to find out).
Make sure you run the pw+ph codes using a clean directory as your outdir.
