Hi,

I'm using Payne-Gaposchkin release
to run the BBHLowRes.par  example

basically, follow this instruction https://arxiv.org/abs/1305.5299
<https://arxiv.org/abs/1305.5299>

however, it seems that the simlution terminated too early.
this is the plot of data in BH_diagnostics.ahX.gp i got

​
i noticed that in the output of "sim list-sim"
it says "Warning: job status is U"

and this is the from .err file in output-0000  (partially)
================================================

Writing backtrace to mybbh/backtrace.0.txt
Aborted (core dumped)
=====================================================


I can't figure out what's the problem, even where to get the error message
correctly.
I have try to change the initial data given by "two puncture", and it turns
out that those BH can't move too far as above, although they really changed
the trajectory.


Environment:
virtualBox
8G RAM assigned
Ubuntu 16.04.1



Could anyone give me some hint~


Thanks a lot !
Cory
