If I comment out the above if block (plus two more pretty much identical ones in m_forstr.F90 and m_stress.F90) most of the tests run fine (I guess the other ones really do need fock). I am a bit baffled why gfortran compiles this in such a way (at -g without any -O as well) that we get a segfault here. I now tried with FCFLAGS='-g -O2' and then the test suite runs fine, so reassigning to gfortran-9 for now, do you have an idea what's going on? (I filed this one upstream as well: https://github.com/abinit/abinit/issues/25) Michael
