"Possible Parse Error: Insufficient memory to allocate intermediate image
storage."
"Fatal error in parser: Cannot access data in file."
The message above appears sometimes after restarting the render, following a
render interruption. Shutting down POV-Ray and starting up again solves the
problem. I guess that all memory is not cleared after a render interruption.
Is this a bug?

I once encountered this, too.
I had the impression that this happens when you interrupt POV-Ray while it is
busy generating a (large) "function image".
It is a bug at any rate.

It has to do with it seems with image_maps, and especially with large ones I
guess, possibly in combination with large meshes... Oh dear, I am afraid I
am not too specific. I shall observe the thing more closely before sending
in a bug report.

That's much more detailed than what I'm used to at work. Sometimes it feels
like:
Customer: "Something's wrong."
We: "Okay, we'll correct something in the next version."

the intermediate image storage, at least on windows, requires a certain amount
of contiguous virtual address space (not physical memory), determined by the
dimensions of the image being rendered. if the virtual address space is
fragmented this allocation request may fail. it's a known problem I have to work
around by providing a fall-back means of accessing the intermediate image data
(currently it's done via the above-mentioned memory mapping of virtual address
space to physical disk space).

LOL! To tell the truth I was just feeling like that customer....

Yes, that seems to be the problem, Chris.
