Latest BG in master branch crashes when run with one cluster on Linux

[stiber]

What kind of issue is this?

• Bug report
• Feature request
• Question not answered in documentation
• Cleanup needed

This problem appears to arise, at least partly, when BG is compiled without HDF5 support and the output file directory doesn't exist.

When we run the simulator with one cluster, we get a segmentation fault at the end of the simulation, just after it outputs "Cluster: 0 total_incoming_synapse_count: 0" but before it outputs the elapsed time information.

When we run with two clusters, the simulation completes without error.

When we create the "results" directory, then the simulation runs fine.

What is affected by this?

How do we replicate the issue/how would it work?

1. Edit Makefile to set "CUSEHDF5 = no"
2. make growth
3. Make sure results directory doesn't exist
4. ./growth -t configfiles/test-tiny.xml -c 1
5. ./growth -t configfiles/test-tiny.xml -c 2
6. mkdir results
7. repeat steps 4 and 5

Expected behavior (i.e. solution or outline of what it would look like)
