Running large .pov file fails without error message

[PlanetEarthSoftware]

I have a large 10 GiB .pov file I have generated and was hoping to render, POV-Ray is 64 bit and I have 16 GiB of memory. No error message is shown.

POV-Ray Version

• Incarnation: POV-Ray for Windows
• Affected build version: 3.7.0.msvc10.win64

Runtime Environment

• Operating system: Microsoft Windows [Version 10.0.19043.1165] Windows 10 Home 21H1
• Hardware architecture: x86-64
• CPU model: Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz 2.90 GHz

Steps to Reproduce

1. Start POV-Ray 64 bit
2. Hit the Sel-Run tollbar icon
3. Select the large .pov file [ download and unzip https://genethomas.com/tmp/500.zip ]

Expected Behavior

Should render file and display the image or say it has run out of memory or some other error.

Actual Behavior

The rendering finishes almost immediately and a blank image is shown. The messages windows does not show any errors that have not occurred with good runs I have done before.

The integrated editor of POV-Ray for Windows is based on a rather outdated 3rd-party component ("CodeMax"). That component, to the best of my knowledge, has remained unchanged since 32-bit times, so may be fundamentally incapable of handling files larger than 2 or 4 GB.

POV-Ray may still be able to render the file, using "Select File and Render" from the "Render" menu (Alt+S). This will just try to parse and render the file, without opening it in the editor.

When I do that is flickers as if rendering for a second then shows a blank black final image in the new window. The same blank black is written to a .png file. No error messages are show here either.

The following is shown in the Messages window, nothing that successful renders I have done have shown,

I have zipped up my large .pov file that exercises this fault, it can be downloaded from https://genethomas.com/tmp/500.zip

Having downloaded the ZIP file, I see a single .pov file of ~10 MB size in there. I take it that is all that's needed to (try to) render the scene?

Be advised that it may take a couple of days before I get around to digging into the issue.

yes. it is one huge mesh. It #includes "colors.inc".

That single .pov file is 10 GB not MB. Has there been any movement on this?
