I have a POV file, created in L3P, which rended fine in 3.6.1c but does not
render correctly with 3.7.0.beta.16. I have tried both SSE2 and non-SSE2
versions of the EXE. Output size does not seem to matter, nor
Anti-Aliasing. As far as render settings I was using QUICKRES.INI in all
cases. I'm pretty amature with PovRay so may be missing a setting that
needs changed for 3.7. I did take a look through the changes documentation
and nothing jumped out.

I realize including the POV file would help but the POV file is quite long,
6848 lines, to include in this message. I can send file upon request.

Corey.

Well, for starters, could you please be a bit more precise? Is there an
error message, a crash, something else?

I can report the same Problem.
I have a Scene what renders in Pov 3.5 and 3.6.x, but causes an access
violation during parsing in Pov 3.7 (tested in Beta 15 and 16, pvengine.exe
and pvengine-sse2.exe).

It is a Blob-Object on which I distribute lots of Mesh-objects with help of
the trace - command.

Here you can find the File:

OS is Win XP Prof SP2 on Intel Core 2 Duo 6400 / 2 GB RAM

Thanks for this, I have been able to replicate the problem here.

While I know why it's crashing (it relates to an invalid element when copying
a CSG object), I don't yet know why it's getting that way since it takes so
long to get to the point where the crash happens (about 10 minutes of parsing
in debug mode).

It would help a lot if you could, if possible, simplify the scene such that
the crash happens sooner. In case it helps, the problem is triggered by the
line 'object{MA2_HaR}' at line 2912 of the file. However the real problem is
earlier than that; the object copy mentioned above just demonstrates it.

regards,

-- Chris

Yes, I can help you there.
The simplified Scene would not crash anymore :(,
but if I include the Object in a whole Scene it would crash faster (after
0:40 min instead 2:12 min on my machine):

While making this Zip-archive I found another access violation while
cancelling the parsing (pressing Alt+G and using the Stop-button result in
an error) or using the #error-Stream...
Just change Line 27 in "#local AffenFell = off;" and try again, I
constructed an #error statement what causes this error.

yours,

Thomas

I didn't get this error - is there a particular time that the button has to
be pressed at ?

It would help me if you could do whatever you need to do to make this happen
and save a mindump when that option is offered to you, then zip it up and
email it to min### [at] povrayorg.

The Minidump is on its way to your Mailbox...

How I get the access violation:

Just run "Moosaffen_unter_Baum.pov" until Pov crashes.
On my Computer it crashes if I attempt to use the error-stream, too. That is
just that what I build into the File (for testing ;) ).

Just bevor ist crashes, there is some debug-text like
"Zeile: " a number and a random-looking string of ".", "F", "3" and
whitespace.

I hope, you can find it now.

This is fixed now, thanks.

got it, thanks - could you also do one with the non-SSE2 build and send it?

thanks,
