[QE-users] Error in reading wfc files in ph.x and projwfc.x

[Paolo Giannozzi]

If you have access to Intel support, try the latest update, v.16.0.4. If
you do not have access, or if it doesn't solve the problem, you have to
figure out what is wrong in your data and where the error happens:
typically there is a single routine that fails. Try to compile the
problematic routine(s) without optimization first of all.
