[petsc-users] segmentation fault when using AOCreateBasicIS with v3.3.6 in Fortran

[George Pau]

Hi,

I called the AOCreateBasicIS by

call AOCreateBasicIS(is_global,PETSC_NULL_OBJECT,global_map,pierr)

where I am trying to map the indices partitioned by the partitioner
(is_global is obtained through  MatPartitioning-related functions followed
by ISPartitioningToNumbering) to the global petsc numbering.  I wanted to
use the natural numbering for the second argument. But I am getting a
segmentation fault at

#0  0x00000000006eae2d in aocreatebasicis_ (isapp=0x7fffffffda40,
ispetsc=0x0, aoout=0x7fffffffdaa0, ierr=0x17c9644) at
/home/gpau/tough_codes/esd-tough3/build/Linux-x86_64-MPI-EOS-eco2n-Debug/toughlib/tpls/petsc/petsc-3.3-p6-source/src/dm/ao/impls/basic/ftn-custom/zaobasicf.c:29

I didn't have this problem with v3.3.3 where PETSC_NULL is used instead of
PETSC_NULL_OBJECT for the second argument

Any help will be appreciated.

Thanks,
George
