cp.x works with DFT+U (or at least, it was working the last time I tried)
but maybe there are problems under some circumstances with recent changes.

Dear Paolo,
Hi again.
In non_dft+u calculation, I have no SEG. FAULT problem.
Is cp.x inconsistent with dft+u?

Dear Paolo,
Hi.
Thank you so much for your reply.
1- I am using the cp.c included in QE-6.7. Yes, I am using DFT+U.
2- The Intel compiler 2018 update 4 is used for building.
Thank you again.
Bests,
Mahmoud
Hi Mahmoud
1. are you running CP (which version?) with DFT+U?
2. which compiler are you using? several old versions of the Intel compiler
have problems with that part of the code

Dear QE users,
I am running cp.x for a given input file. The run is completed but when the
program starts to write .save
files, I get the following SEG. FAULT:

It should be mentioned that:
1)- the "ulimit -s unlimited" recipe has already been applied.
2)- The Example-1 of cp.x for SiO2 has been run successfully without such an
error.
Any comments is highly appreciated.
