Just an update.

The problem is reproducible even when mpich2 is compiled with gcc 4.2,
absoft 8.0.

$mpif90 -show
f90 -I/home/raju/software/compiledLibs/mpich2_1.0.5p4_gcc_4.2.0_absoft_8.0/include

$mpif90 test.f90

$mpiexec -l -n 4 ./a.out
rank 3 in job 7  node1.jit.mae.cornell.edu_38952   caused collective
abort of all ranks
  exit status of rank 3: killed by signal 11
rank 1 in job 7  node1.jit.mae.cornell.edu_38952   caused collective
abort of all ranks
  exit status of rank 1: killed by signal 11

When I ran the program via gdb using

mpiexec -gdb -l -n 4 ./a.out

the code seems to segfault at line 19 when it calls func1. AFAIK there
is no memory violation in that part.

I will try to recompile the mpich2 libs with --enable-g=meminit,dbg
and see if there is anything new to report.
