[CPMD-list] Compilation problem: Intel Fortran 9.1 and em64t

[Vladimir Stegailov]

Dear colleagues,

could you give some hints concerning the compilation problem.

I am trying to compile the code on the Xeon based system with IFC 9.1 and
MKL 9.0.

The Makefile options are

FFLAGS = -c -r8 -w95 -O2 -pc64 -tpp7 -unroll -cm -tune pn4 -arch pn4
LFLAGS = -L/opt/intel/mkl/9.0/lib/em64t -lmkl_lapack64 -lmkl_em64t
CFLAGS = -c -O2 -Wall
CPP = /lib/cpp -P -C -traditional
CPPFLAGS = -D__Linux -D__PGI -DFFT_DEFAULT \
               -DPARALLEL -DMYRINET -DLINUX_IFC -DINTEL_MKL
NOOPT_FLAG =
CC = mpicc
FC = mpif77
LD = mpif77

The executable is compiled successfully. However it can not start even
with example scripts. 

Console report is like follows

forrtl: severe (174): SIGSEGV, segmentation fault occurred

The output file has three lines

FREEM | COULD NOT FIND POINTER           182934130704

When I try to compile in the debug mode (with "-g") the process stops with
an error message 

/lib/cpp -P -C -traditional -D__Linux -D__PGI -DFFT_DEFAULT -DPARALLEL
-DMYRINET -DLINUX_IFC -DINTEL_MKL   ./formf.F ./formf.f

/formf.f -o  ./formf.o
fortcom: Severe: **Internal compiler error: segmentation violation signal

occurred in a Software Problem Report.  Note: File and line given may not
be explicit cause of this error.

compilation aborted for ./formf.f (code 3)
make: *** [formf.o] Error 3

I have made a try to increase the stack size (inserting 'ulimit -s
unlimited' in the .profile). However the result is the same.

As I understand it seems to be an ICF problem. However this 9.1 version
works fine on other platforms (not em64t).

What could be done to solve the issue?
