DFTB test running problem

[boulf... at googlemail.com]

Hi everybody,

the DFTB test h2o-32_4.inp ( located in cp2k/tests/DFTB/regtest-
nonscc) is an MD run of a box of H2O molecules. Running the test is
ok, but increasing the number of steps up to 500 with 0.2 fs timestep
using NPT_F ensemble crashes with the following error:
#################

*** 12:48:02 ERRORL2 in cp_fm_cholesky:cp_fm_cholesky_decompose

3 velocity_verlet
2 qs_mol_dyn_low

CP2K| Abnormal program termination, stopped by process number 0

Does anybody have a clue about the reasons of this or how to fix the
problem ????

Thanks in advance.
