Ciao Toon,
I compiled on this kind of architecture:


                    +-----------------------------------------+
                    |  Welcome to CASPUR PWR5!  |
                    |                    AIX 5.3ML4                |
                    +-----------------------------------------+

<teo at pwr503 /data/afz/teo/CP2K_suite/cp2k>tools/get_arch_code
AIX-PowerPC_POWER5

<teo at pwr503 /data/afz/teo/CP2K_suite/cp2k/arch>mpxlf95_r -qversion
IBM XL Fortran Enterprise Edition V10.1 for AIX
Version: 10.01.0000.0002

and this is the arch file that I'm using:
----------------------------------------------------------------------
CC       = cc
CPP      = /usr/ccs/lib/cpp
FC       = mpxlf95_r -qsuffix=f=f90
LD       = mpxlf95_r
AR       = ar -r -X64
DFLAGS   = -D__AIX -D__ESSL -D__FFTSG -D__FFTESSL\
            -D__parallel -D__BLACS -D__SCALAPACK
CPPFLAGS = -C $(DFLAGS) -P
FCFLAGS  = -O2 -q64 -qarch=pwr5 -qcache=auto -qmaxmem=-1 -qtune=pwr5
FCFLAGS2 = -O0 -q64 -qarch=pwr5 -qcache=auto -qmaxmem=-1 -qtune=pwr5
LDFLAGS  = $(FCFLAGS) -L/afs/caspur.it/user/s/simonem/LAPACK -L/usr/ 
local++/SCALAPACK/pwr5/ -bnoquiet\
            -bmaxdata:0x800000000  -bmaxstack:0x80000000
LIBS     = -lscalapack -lblacssmp -llapack_pwr5 -lpesslsmp -lesslsmp - 
lmass -lhm

OBJECTS_ARCHITECTURE = machine_aix.o

pint_types.o: pint_types.F
         $(FC) -c $(FCFLAGS2) $<
----------------------------------------------------------------------

That is exactly the one you can find in the repository with the name:

AIX-PowerPC_POWER5.popt

If you have a quick input file that shows this memory leak problem I  
can try to run it on the CASPUR machine and see
if there I can reproduce the same problem.

Let me know.
Teo
