[FLASH-USERS] Suddenly FLASH doesn't work anymore on Linux desktop

[Andreas Ekenbäck]

Hi all,

I have been running FLASH2.5 on my desktop computer for a while, but 
since a couple of days it suddenly doesn't work anymore.

Some libraries have been upgraded since the last successful runs of 
FLASH. Specifically there was an upgrade of bzip2 and libbz2 that I 
can't undo. I have reinstalled MPICH2, ifort and icc today without 
improvements.

I can run for example the sedov setup, but we have 2 own setups that 
suddenly do not work anymore. Both setups use particles, otherwise there 
is nothing fundamentally different. Our setups output the first chk- and 
plotfiles (0000) and then crashes at the first time step. And note that 
it's only on this computer that our setups do not work.
The longest error messages we have been able to achieve:
----

System information:
- Linux hybrid.irf.se 2.6.22-14-generic #1 SMP Tue Feb 12 02:46:46 UTC 
2008 x86_64 GNU/Linux
- ifort 10.1.012

So...
- anyone had the same problem?
- any ideas how to continue problem solving?
- is there some indirect dependence on libbz2 (i.e. could that upgrade 
be guilty?)

Thankful for any help
