I am trying to run a Fortran program that exercises some of my computational
kernels.  The program does not use MPI, just OpenMP.  I have compiled
it for a small case and that runs fine and gives the correct results.
However when I recompile it for a realistic cases (the same source
is used, only a bunch of parameter statements are different), it
segfaults at line 13 of the main program:

[knl00 tests] ../mc/x.testwf.12c-11_states-pn  c12_11states-pn.in

Line 13 is the very beginning of declarations, not an executable statement.
It is the first non-comment line and is:

      use random2

random2 is a module that defines some subroutines.  It is not changed
by the parameter statements that are different for the working and failing
cases.

Here are the working and failing executable sizes:

   text       data        bss        dec        hex    filename
2459352     124772    24979752    27563876    1a49764    x.testwf.4he-pn

Here is how the main program is compiled and module linked:

ifort -Imods.libgen -FR -g -O0 -qopenmp -lpthread -qopenmp-report -r8  -WB -traceback -fpe3 -I../common/ -I../mc/ -fpp  -DSPIN_SUF= -DPARAMNUC=nclude/paramnuc.12c-11_states-pn -DM0_DIV=1 -DDOCASE=0 -DPARAMCASE=nclude/paramcase.12c-11_states-pn -c -g testwf.f

ifort -g -mcmodel=medium -traceback  -fpe3  -qopenmp -lpthread -qopenmp-report   -o x.testwf.12c-11_states-pn testwf.o do_adlb_no.o dmem_fake.o adlb_fake.o \

[knl00 mc] which ifort
/soft/compilers/intel/bin/ifort


This is in ~b21541/gfmc/mc  .

This test case runs fine on blues.

Any suggestions will be gratefully received.
