xdm Fortran runtime error: Attempt to DEALLOCATE unallocated 'grad_psic'

Hello,

with up-to-date Q.E., I am getting this error with spin-orbit and xdm, see below.

Looking how to fix it in the code, please give some hints :

     iteration #  1     ecut=    40.00 Ry     beta= 0.40
     Davidson diagonalization with overlap

---- Real-time Memory Report at c_bands before calling an iterative solver
           292 MiB given to the printing process from OS
           436 MiB allocation reported by mallinfo(arena+hblkhd)
         12875 MiB available memory on the node where the printing process lives
------------------
     ethr =  1.00E-02,  avg # of iterations =  1.0
