[Pw_forum] Possible bug

[Pablo García Risueño]

Dear Espresso developers

I have found a behavior in Quantum Espresso that I have found rather
surprising: writing or not the << prefix >> field in the input of pw.x
sometimes provides outputs (potential files generated with pp.x) rather
different to the correct one; sometimes, the run crashes; and sometimes the
run provides the correct result. In the former case, the difference in the
results is enough to give completely wrong results in programs that use
this output as its input. I attach a file with more information on this
issue, just in case that you think that it is undesirable and you want to
avoid it.


Best regards.
