[Pw_forum] tetrahedra and vc-relax

[Mitsuaki Kawamura]

Dear Dr. Ricca

This occurs because some variables for the tetrahedron method are
deallocated before the final SCF calculation (and it is not allocated after
that).
I attached the patch to fix this bug. Please apply this as
$ patch -p1 < tetra.diff

Best regards,
Mitsuaki Kawamura

Subject: [Pw_forum] tetrahedra and vc-relax

Dear all,
I'm trying to perform a "vc-relax" calculation using the tetrahedron method
with QE v 6.1.
The calculation stops after having printed the final geometry, during the
final scf step.
It does not write any error and the scheduler only reports a segmentation
fault.
I have tried with both tetrahedra and tetrahedra_opt, but I have the same
issue.
The problem is not there if I do a "relax" calculation.
Please find attached, the input and output of an example.
Thanks in advance!
Regards,
Chiara Ricca
