Line 625 is the start of a series of #if's for each frame starting at 1. 
The clock variable is not referred to at all.

I used:
povray +w1920 +h1080 +KFI1 +KFF360 Scene_def.pov

I had the same warnings as you.

I did a search and replace to make the path to the include files 
relative, no other changes to the source.

Still running after over 20 hours, but no errors so far.
160 frames generated of what looks like to be a wonderful animation.

Is the bug limited to the Windows version?

I want to reproduce it before trying something from Christoph Lipka
(clipka).

Nope, but tied to the system memory management if the symptoms are
correct (rare condition), and if I got it correctly from the explanations.

Happens always after the first frame on Mac.
It takes a lot of time before all memory is released after a frame,
maybe too long?

Congrats, you've just volunteered to be our guinea pig for a solution :-)

I've shelved a few files in change #5817 (Workspace cli-pc-7) that 
should fix the issue if our assumptions about the root cause are 
correct; as far as I understand you should be able to access those 
files, so if you wouldn't mind test-driving them...?

Sure - no problem! FYI - I also tested it on another PC (128 GB RAM with 24
threads)... same issue there.

So this is the weird thing: including only one or a few of the *.inc files and
then, there is no error anymore! So it seems the size of the scene matters...

I'm somewhat having a deadline... would you be able to send me the 360 frames
rendered at 1920 x 1080 (AA 0.3)?

Yvo was able to help investigating this issue, and it seems that yes, 
memory consumption is the key after all: The backend seems to take 
longer to free the allocated memory than the frontend is willing to wait.

Great news - when do you think this will be resolved? In other words, when will
I be able to download a version without this bug? Just worried I'll miss the
deadline :-(!

I haven't been following this thread closely so maybe this won't be any 
help, but nevertheless I feel compelled to mention the six resource leak 
bugs uncovered by Coverity ... CID's #967298-#967303 ... these were 
found in either parse.cpp or parsestr.cpp

correction ... five bugs starting at CID #967299 /instead of/ #967298
