Dear colleagues,<div><br></div><div>I ran into a problem when trying to
run pp.x for my surface slab. The program stopped after a few seconds
and error lines appeared, indicating two errors, namely: free() invalid
memory, and munmap_chunk() invalid pointer. </div><div><br></div><div>I did some research and realized that
it was the problem with the C (or C++) compiler related to malloc()
function and it was suggested to check the code I was running. Also, I
saw elsewhere that Dr. Paolo Giannozzi once stated that it's not the
problem with QE. Therefore, I have no idea how to overcome this problem.<br clear="all"><div><br></div><div>Has anyone experienced similar cases? Can you give me some advice? All suggestions are highly appreciated.</div><div><br></div><div>(By the way, I am running QE on a 64-core AMD Ryzen 3999X workstation, if it helps)</div><div><br></div><div>Best regards,</div></div>
