[Pw_forum] Jobs can't finish with the tag of vdw_corr

[Giovanni La Penna]

I have the same problem running PW relax calculations
with:

vdw_corr='grimme-d2'

I noticed the core dump when writing the
forces at scf convergence. No errors if no
convergence is achieved (electron_maxstep=1).
Then I found that removing

tprnfor=.true.

the scf calculation ends normally. But tprnfor
is true by default for relax calculations.
It seems a problem related with vdw forces.
