To the QE developers,<br> In the new version of 4.3.2 Quantum Espresso, if I use 'vc-relax', I find that at the end of relaxation, the code does a new self-consistent calculation. However, if I turn on Hubbard U, the code crashes at the last self-consistent calculation due to some segmentation fault. If no Hubbard U is used, then everything is fine. I am wondering whether any one else on the forum has similar experiences and whether this might be a bug in the code or due to some compilation problems.<br>
