SEGV on 64 bits program (works on 32bits)

hello,

i'm using a scientific library (called MUMPS), which needs BLACS ans Scalapack.

Everything works well on sparc machines, with Sun HPC ClusterTools 5.

Now, i want to use it on Sun V40z (opteron) machine, solaris 10 and Sun HPC ClusterTools 6.

And it fails with more than 2 processes:

nemo-henry% mprun -np 2 ./dsimpletest < input_simpletest_real

...

Solution is 0.9999999999999984 1.9999999999999997 3.000000000000001

3.9999999999999995 5.000000000000001

nemo-henry% mprun -np 4 ./dsimpletest < input_simpletest_real

Job cre.79 on nemo: received signal SEGV.

Here i have some notes on how i'm compiling these libraries.

thanks for help
