[FLASH-USERS] The problem "Segmentation fault"

[Alexander Wagner]

I'm just forwarding the exchange i had with Zhang to the list as I hit 
the wrong reply button again and left out the list.

Zhang, what mpi library did you build with? Are you sure mpi works 
properly on your machine?

I wonder if this is the same problem i had once on a CentOS cluster with 
Intel Xeons and FLASH3.2, where it would segfault before it even reached 
call Drivier_initFlash() in Flash.F90. Our sys admin couldn't solve the 
problem either, but we had another cluster to work on, so we dropped the 
issue. That being said, it really should work, though.

Best wishes,
Alex
