I've been having a problem with running a render recently. The scene in
question is parse-heavy (it takes about 30 minutes to parse on my iBook),
but I don't know if that's relevant. It gets to about 40 million tokens
(not always the same number, though) before throwing the following error:
"The POV-Ray core rendering code threw an unhandled exception.
The backend thread has been shut down and you will not be able to perform
any more renders.
It is STRONGLY RECOMMENDED that you save your work and exit POV-Ray now.
(Note that if internal structures have been damaged POV-Ray may crash
immediately after you click OK)."
....and the following parse error in the messages pane:
"Parse error: out of memory. Cannot allocate 90720 bytes for fn:
FunctionEntry."
This is from the standard POV 3.6 download, installed under XP Pro (service
pack 2) on a 2.7GHz AMD-FX55 with 2GB RAM. The same scene runs fine on my
office machine (0.9MHz Win98, POV 3.6 again), and my iBook (POV 3.6.1 Mac).
It can't be running out of memory; the peak usage should be no more than
600MB.
Has anybody else seen this error, and, if so, know why it occurs?

Are you doing any file I/O in your scene? If so, make sure you have the
proper closing parantheses in your #write directives. In my current
project, I missed one and it would cause POV-Ray to crash with the error
you gave. For example, this:
#write (file2,"
object {
TrackTie
Reorient_Trans(y,",raxis,")
Reorient_Trans(z,",(point2-point1)*(x+z),")
Reorient_Trans(",(point2-point1)*(x+z),",",point2-point1,")
translate ",point1,"
pigment { color rgb <1,1,0> }
}"
Notice the missing ")" at the end? That's what was causing my problem.

I am, but I don't think that's the problem. As I said, the same scene (with
accompanying data files) works fine on two other systems, failing only on a
specific machine.
I guess it's possible that one of the data files is becoming corrupted
somehow in the transfer... I'll have to check that.
