[CPMD-list] crashes during saving RESTART file, using Vanderbilt PPs

Hello all,

does anybody know how to fix the following problem with CPMD-3.5.2 ?

Molecular-dynamics runs (CP, with Vanderbilt pseudopotentials!) crash 
during saving the RESTART file to disk.
It happens AFTER step no. 499. (I.e. either at the end of the run or during
the run when saving is forced by the STORE option. The current step number
must be > 499 (or  400? I have not tested this detail)).
The problem occurs regardless I use the OLDCODE or the NEWCODE option.

The problem occured on all tested platforms (linux-intel, linux-alpha, IBM SP)
both for serial and parallel runs. 
There are thousands of pointer values and the final error message at the 
end of the output file:
 PROGRAM STOPS IN SUBROUTINE FREEM|  NO SUCH POINTER

The RESTART file is corrupted. Below I give an example of my input file.
Thank you.

Martin Konopka.
