[QE-users] Segmentation fault - invalid memory reference

[杨世隆]

To whom may care

I am running example12 in pw with QE6.4.1 on MacOSX10.14.6. 
The example is about noncollinear/spin-orbit case with DFT+U and Ultrasoft pseudopotentials. 
I run 
./run_example
In the terminal and get errors like this 
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error: 

And a long list for this backtrace (if it’s important, I will post it next time) 
And I have this at the bottom of the terminal
mpirun noticed that process rank 3 with PID 0 on node nbp-146-110 exited on signal 11 (Segmentation fault: 11).
--------------------------------------------------------------------------
Error condition encountered during test: exit status = 139

This error occurs whenever the calculation starts scf 

As additional information, I compile the QE with the fftw3 come with octave, otherwise it wouldn’t work. 

Thanks a lot for whom would like to help! I’ll be so grateful!
