[CPMD-list] Stress calculations with USPP

Guys,

is anyone able to calculate stress tensor in 
simulations with ultrasoft Vanderbilt PPs ?

Both versions 3.5.2 and 3.5.3 give me the
following message before crashing:
 ================================================================
 ==                     FORCES INITIALIZATION                  ==
 ================================================================
 EWALD SUM IN REAL SPACE OVER  1* 1* 1 CELLS
 ***    STRESS| THE NEW SIZE OF THE PROGRAM IS  139280 kBYTES ***
 ***    DQVAN2| THE NEW SIZE OF THE PROGRAM IS  139280

I've got the same crash on multiprocessor SunFire machine and 
Linux workstations, but have never had problems with the stress 
calculations while using norm-conserving PPs (even with much more
memory).
