Dear developers and users,
I tried to run GPU version of QE for electron phonon coupling calculation on an
a100 card. The structure relaxation and self-consistent calculation are
successful. However, when I did phonon calculation, my job crashed with a
strange error:

I am not an expert of coding, but it seems like the line 325 wasn't recognized,
which is fairly strange. I don't know how to solve this problem, and I am glad
if anyone can help me.
Yours,
