Thank you so much for pushing forward for a new release stepping of Povray.

I am new in this forum. I have been using V3.7 for some years and now trying out
the beta releases. I am re-rendering some of the old competition sources and
found a source file that crashes at parsing in beta.3 and also beta.2, but runs
fine on the v3.7. I have a pretty standard machine running Win10.

I don't know whether you are interested to use such source for debugging and how
I can contribute such source?
