Dear professor.
When I abinit the t12.in according to the guidance, the t12.out was terminated at the DATASET2. The log file contains some information at the end as follows:

ioarr: writing density data
ioarr: file name is t11o_DS2_DEN
ioarr: data written to disk file t11o_DS2_DEN
forrtl: severe (173): A pointer passed to DEALLOCATE points to an array that cannot be deallocated

I have the same problem with the intel compiler (I'm using abinit 6.6.2 with ifort 2011 and mkl 2011). It comes from statements like 95_drive/scfcv.F90:1787

Code: Select all

 if(associated(grhor))then
   deallocate(grhor)
   nullify(grhor)
 end if

where grhor is a pointer. Apparently there is some controversy about the fortran standards regarding deallocating pointers; intel is very strict about it while gfortran is not as strict. If you switch to gfortran, this code does not (should not) produce an error. I'm new to fortran pointers so if anyone has a workaround, I'd appreciate it, otherwise I'll try some things and see what doesn't crash.

I think this may be the same error:

Changing some of the pointer declarations to
real(dp),pointer :: elfr(:,:) => null(), grhor(:,:,:) => null(),lrhor(:,:) => null()
seems to fix the problem for me
