although I am not a QE developer:<br>
Please compile QE with debugging symbols: "-g -traceback", only
then one can immediately see where in QE something goes wrong. As
it does not cost any performance, just do it every time.<br>

<div dir="ltr">so does anyone have any ideas I have checked for
any compiler issues, like libraries compiled from different
sources, but I still get the same seg fault, I even switched to
a previous implementation of Quantum espresso but the issues
still persist</div>

<div dir="ltr">thanks for the kind reply, so I just recently
downloaded quantum espresso, and this problem persist when
I just run pw.x without specifying any input files, it
also of course fails with the example files as well under
the PW directory. Do you think it has to do with the
version of QE I am running which is 6.3?

<div dir="ltr">As I mentioned in a previous
entry, we have been experiencing the same very
intermittent error for both pw.x and ph.x .
We have no ideas about the origin except that it
seems to be related to the version of the
openmpi library. For 3.1.1-intel-2018 and
3.1.0-intel-2018 the error is rather frequent.
For 2.1.0-intel-2018, it seems to happen less
frequently. It appears for QE 6.2.1 and 6.3.
Unfortunately, it does not appear for very
short jobs, but I will be happy to provide a
sample input file for an intermediate size job
if that will be helpful..... Thanks, Natalie
