[Pw_forum] Does PWSCF have a bug when optimizing the structure in one electric field?

Hi, Dear Users,

I tried to optimize the molecular structure in a saw-like electric field using espresso-3.2. However, the optimization is always failed. I checked the forces through the numerical method. It seems that the forces in a electic field are wrong. Maybe the version I used is old. Does anybody have the same problem? 

Thanks for your help.
