[QE-users] Segmentation Fault when running pw.x

[Tobias Kloeffel]

Dear Aziz Fall,
although I am not a QE developer:
Please compile QE with debugging symbols: "-g -traceback", only then one 
can immediately see where in QE something goes wrong. As it does not 
cost any performance, just do it every time.

Regards,
Tobias Kloeffel
