Segmentation Fault

[stoiver]

I have installed anuga-viewer on ubuntu 16.04.

The viewer seems to work fine on most sww files, but I have a large sww file which is 1.7 GB (output of the towadgi validation test), which fails with a segmentation fault at the 129,000 sec timestep.

(This worked fine on Ubuntu 14.04)

Using gdb and valgrind doesn't give much information, just crashing when a new thread (Thread 9) is created.

Here is the backtrace:
