I have received the following compiler error when compiling VASP 6.2.0:

mpiifort -qopenmp -free -names lowercase -assume byterecl -w -xHOST -Ofast -march=core-avx2 -I/opt/intel/oneapi/mkl/2021.1.1/include/fftw -c nonl.f90 nonl.f90: catastrophic error: **Internal compiler error: segmentation violation signal raised** Please report this error along with the circumstances in which it occurred in a Software Problem Report. Note: File and line given may not be explicit cause of this error. compilation aborted for nonl.f90 (code 1)

Using

ifort (IFORT) 2021.3.0 20210609

and

Intel(R) MPI Library for Linux* OS, Version 2021.3 Build 20210601 (id: 6f90181f1)

Any ideas on how to fix it gratefully received!

Changing the compiler options or the code may make the bug stay hidden, but this bug is in the compiler, not your code. You will need to provide the source file, nonl.f90, any include files that it requires, and the sources of any modules that are used in nonl.f90.

Unfortunately I can't share the source under its license. I'll contact the developers.

Thanks!
