[Pw_forum] errors in *.err files

[Goranka Bilalbegovic]

Intel compilers at the cluster I am using recently have been replaced with
gfortran/gcc. I compiled  espresso-5.0.2 an did not notice anything unusual
at the configure and compilation steps. However, while running pw jobs (my
own and examples) I found that *.err  files (from sge scripts) are not
empty:

The results from examples are OK, but I would like to know why lines like
this appear. Is it dangerous ?
Thank you very much for your answer.
