<div dir="ltr">I am not sure what is the output for that particular line, but the last part of the output looks as given below. For different instances of the run, the particular iteration changes, but the boxed error message returned by phonon.f90 is always the same.

<div dir="ltr">This segmentation fault issue has also appeared for
us in another QE code. Perhaps it is a totally unrelated
problem which we find related to the openmpi package compiled
with intel-3.1.1-2018 and intel-3.1.0-2018. In our case,
compiling with openmpi package compiled with intel-2.1.0-2018
usually (not always) solves the problem. Compiling with a much
older openmpi package solves the problem, but is not viable for
the current configuration of our cluster. Since no one else
mentioned the problem until now, we think it may have to do with
our internal setup??? The error is very intermittent,
occurring at different places in the code for the same input.
The common aspect of this error to the one in the original
message is <a href="http://libpthread-2.12.so" target="_blank">libpthread-2.12.so</a>. Most reliably
we see the error in ph.x with part of the error message:

I'm afraid it's a problem with MKL-blas ZDOTC, which
must<br>
return a complex(dp) result. Very strange, because if
you grep<br>
the source code, we have declared it: complex(dp),
external::zdtoc<br>
<br>
Can you tell us your compiler and MKL version? can you
add<br>
DFLAGS+=-Dzdotc=zdotc_wrapper<br>
to the QE make.inc and recompile both (QE and GIPAW)?<br>
<br>
Best wishes,<br>

Hello,<br>
<br>
I've been trying to do g factor calculations in GIPAW
working for a few days now. I keep getting a
segmentation fault (below) no matter how I compile it
on our cluster. Does anyone have a good idea of what
might be causing this?<br>
