Dear all,

I have compiled QE 6.0 with GNU compilers, intel mkl for all libraries except fft which i used fftw3 for it. I used MPICH for the MPI libs.

I also compiled successfully gipaw version 6.0 using the same libraries. I started running the quartz example. SCF went successfully without any problems.

GIPAW failed and gave the following error:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:

Segmentation fault (core dumped)


I ran using 1 core and 10 cores, both gave similar errors.

I checked other posts and it seems a similar problem existed before in version 5.4. I assumed it was fixed in version 6.0. Can you please advise on what can i do to address this problem?
