For the Intel(R) Core(TM)2 Quad CPU    Q6600  @ 2.40GHz
with ifort 10.1.015, mkl 10.0.1.0.14
operating system Debian (generic), architecture x86_64
Kernel 2.6.24-16-generic
glibc /lib/libc-2.7.so  <--- Intel recommends here 2.3-2.6.x
I compiled lapw1 with:
FOPT =  -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML  -O3 -xW -threads
LDFLAGS = $(FOPT) -L/opt/intel/mkl/10.0.1.014/lib/em64t -lpthread
R_LIBS = -lmkl_lapack64 -lmkl_em64t -lguide -lvml -pthread

Lapw2 with
FOPT =  -FR -mp1 -w -prec_div -pc80 -pad -ip -DINTEL_VML  -O1 -xW -threads

I had to add "limit stacksize unlimited": 
when I put the command in command line "x lapw2 -up" it worked, but if I did 
it with "at" it stopped. 
Maybe some large  value (999999) should be given instead of unlimited. So, in 
the batch file I have:
#!/bin/csh -f
setenv LD_LIBRARY_PATH /opt/intel/fce/10.1.015/lib/
limit stacksize unlimited
runsp_lapw ...

And it was necessary for me to put 
export OMP_NUM_THREADS=1
in bashrc.

Best wishes
