[Swarm-Support] Segmentation fault in cygwin1.dll

[Paul Thompson]

Hello - I'm debugging a program, and I'm getting a segmentation fault
in the cygwin DLL.  I tried looking at the backtrace, but I couldn't
find any mention of any of my own code, so I'm not sure where the
error is.

The program starts the control panel, and initalizes the observerSwarm
and modelSwarm fine (as far as I can tell).  When I hit 'next' (or
'start'), it draws the raster windows, then crashes.  The GDB output
is shown below
