Check the gcc -v output below. The problem will probably occur in all Arch based distros. My notebook has Manjaro, and it is now updated to 7.3.1 as well... and gives the same problem. If you want to reproduce, you can try to compile the fox.tgz package that is in the archive folder of quantum-espresso. That's where the seg.fault happens. I don't think I'll have time this week to compile gcc and make tests. Yesterday I've put quantum-espresso to work using the PGI community edition compilers. So, now it is working and I have to focus on the results. But if I find time, I'll let you know. ---------------------------------------------------- [gerson@tintin ~]$ gcc -v Using built-in specs.
