Hi,

I have compiled siesta-4.1-b3 in parallel on a linux RedHat machine
using intel and mpi, please see attached the arch.make file. However
when I try to run siesta, I receive the following error:

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

Backtrace for this error:

The same .FDF file runs fine with the serial compiled version. 

I do appreciate if you could give me some clue of why this is
happening?

Best wishes
Marj
