Segmentation fault problem

[Zhiping]

Dear all:
I compile cp2k using intel compiler and MKL 11.1.069. Parallel compilation 
is done with intel mpi 4.0.2.003.
While no error is reported during the compilation and I obtain the 
binaries. I found that serial executable works but the parallel one fails 
with 'Segmentation fault (174)' on the test runs.
I follow the threads in several forums and tries several tricks such as 
'ulimit -s unlimited', but still cannot get it working. Could anybody here 
give some suggestions?
Thank you.
Best,
Zhiping
