I'd be tempted to try -wt1 first just to see what happens...

Not a programmer. I have done some *nix debugging on and off over the 
years. From some of those notes.

If you are somewhat routinely getting a core dump:

- Compile povray with the -g flag

- In the shell/xterm where you are running povray and getting a core 
file use the command(1): ulimit -c unlimited

- run povray again to get the full core file.

- Then "gdb <full_path_to_povray> core" followed by one or more of the 
following commands.
(gdb) bt
(gdb) bt full
(gdb) info threads
(gdb) thread apply all bt
(gdb) thread apply all bt full

- If the problem is in one of the libraries povray uses, you can grab 
the debug versions of those libraries, rebuild, repeat. But, I'd bail 
recommending a library update.

--- If the problem is a time out and exit, I am less sure what to do.

- You can run programs under gdb, but here my experience was many years 
ago and singular. I just don't recall. There is eclipse as mentioned, 
but I've never used it.

(1) - One possible gotcha here is if root on your virtual machine has 
set a low hard limit. If so, only root can increase this limit. As 
root(sudo in ubuntu) "ulimit -H unlimited".
