Symmetry detection, VASP 5.3.5

Dear all,

I am running into a problem with the symmetry detection using the ISYM tag. My very simple test calculation finished fine with ISYM=0, but crashed with ISYM=1 or 2 saying:

" VERY BAD NEWS! internal error in subroutine SGRGEN:
Too many elements 49"

The test input files are:

---- POSCAR ---
#fcc
4.05
0.0000 0.5000 0.5000
0.5000 0.0000 0.5000
0.5000 0.5000 0.0000
Al
1
Direct
0 0 0



-----INCAR----
SYSTEM = Al
ISYM=2

----- KPOINTS----
k-points
0
auto
10


Shall I suspect some problems with my inputs or rather with the installation? I shall say that VASP was compiled in the serial more using ifort + mkl on an RHEL6.2 machine.

Many thanks in advance for you help.

David

It looks like not correct MPI implementation.
