[ESPResSo-devel] Open MPI - Issue resolved

[Kai Grass]

Hi,

I was able to isolate the reported error. (Testcase harm.tcl failed  
for 2 nodes with error Error occured: error waiting for process to  
exit: child process lost (is SIGCHLD ignored or trapped?).)
It is caused when closing the piped-gzip-input stream. When reading a  
standard (not zip'ed) file, closing works fine, on a piped-input  
closing immediately collects all errors and throws them.

Therefore, there are at least three possible solutions to the  
problem. A) a catch block around all close statements, B) no  
compressed input files or C) not closing input streams.
I don't favor B) and C) and therefore added the catch blocks around  
the close statements for the testsuite (and the checkpoint_read)  
scripts that caused errors.

Using theses fixes, Espresso now works fine with Open MPI on Mac as  
well as on a Sunfire Cluster.
