Bus error when using MKL 10.3 beta

The system environment is Intel XeonE5450,16GB memory,Redhat Enterprise Linux 5.2,Intel Fortran Compiler 10.1.
In order to use interge8 address, I followed Gennady's suggestionand installed MKL 10.3 beta in my own directory( I do not have root authorization).
I tested a small scale case in which interge4 address issufficient and the compile and link command is:
ifortmkl_dfti.f90 mkl_poisson.f90 ..myprogram.f90-L/myPath.../mkl/lib/intel64/ -Wl,--start-group -lmkl_intel_ilp64 -lmkl_sequential -lmkl_core -Wl,--end-group -lpthread

The compile was successful andLD_LIBRARY_PATH was correctly set. But when I run the object file "a.out", bus error happened.
I know it's about invoking poisson library in MKL because before that everything is ok(I have some screen outputs).
Thanks in advance.

for supportring ILP64 interfaces you have to use special compiler's options i8 ( for Fortran ) and-DMKL_ILP64 for C/C++ compilers.
therefore, compiling for ILP64 you have to use the following command line
ifort -i8 -I/include
See more info into MKL User's Guide, Chapter 3..
