Problem solved, my build (Intel Parallel Studio 2020, xconfigure build script, latest ELPA) was the “culprit”. I switched to GCC 8.3 (also with ELPA and xconfigure, linked with the same Intel MPI and MKL 2020) and now it doesn’t crash anymore. Has anyone else experienced issues with Intel 2020? Oddly enough, all other parts of the QE distribution (well, at least those few I actually have used) seem to work fine for me when built with Intel 2020. Best, Michal
