I went ahead and uploaded the code to github in case anyone is interested: https://github.com/opcom/FX3D

If you import and build in Eclipse on Linux, it works perfectly.
If you import and build in Eclipse on Win7, it crashes. The produced error log is in the repo: https://github.com/opcom/FX3D/blob/master/hs_err_pid5916.log

Hopefully that sheds a bit more light on it.

Cheers.
