Since upgrading to MegaPov 1.2, I have had several irreproducible crashes.
It usually crashes to the desktop with an invalid page fault at the start
of a render, but once crashed in the middle of one. I finally found a
situation that will always crash. The demo scene "bar.pov" (one of the
mechsim demos) will render the first frame without a problem but will crash
at the start of the second frame, just after the message about loading the
mechsim data file. Out of curiosity, I tried it with the demo version and
exception, press OK, etc..." dialogue instead of the CTD.
I am running Windows 98 on a 1.1GHz Athalon with 512Mb RAM.

Oops, meant to say BETA version.
Remember, folks, don't post while sleep-deprived.

Ditto. I was not able to get a scene to consistently fail, though.
The scenes I am working with intermittently crash in MegaPov 1.2
(about half of the time), but never crashed in MegaPov 1.1.
Windows XP Pro with SP2
Let me know if I can provide any further info...

I can confirm this - it happens in the release version as well as with a
MinGW build, it however does not happen on Linux.
I have no means to trace the origin of this problem on Windows so i
can't solve this.

... "bar.pov" works well for me but "collide_fast.pov" crash when
"calculating mechanic simulation" raise at 100% :((
megapov mach-o version (1.20) on panther 10.3.9.7w98

No problem with that scene here either.
Note you have to be more elaborate on what actually happens - 'crash' is
an extremely vague description.

What further info can we provide at this time that will help diagnose
the problem?
BTW, once the source is available, I can compile it in Visual Studio
2003 and run in debug mode to help diagnose the problem.

OK, here is exactly what happens to me. I'll describe what happens when
rendering the mechsim file - the other crashes are similar but not
reproducible.
In the beta version, the first frame will render correctly. When the second
frame starts, the message "Loaded [...] from mechanics simulation data file
bar.dat." appears in the message window. At that point, a dialogue box
appears: "Internal Error: The POV-Ray rendering core threw an unhandled
exception. The backend thread has been shut down and you will not be able
to perform any further 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)." After clicking
OK, the dialogue box disappears, and the following appears in the message
In the final version, instead of the internal dialogue box, the Windows
abnormal program termination dialogue appears: "This program has performed
an illegal operation and will be shut down. MPENGINE caused an invalid
page fault in module MPENGINE.EXE at [hex dump]." After closing this
dialogue the MegaPov thread is terminated, and Windows returns to the
desktop.

'crash' is not much more information than 'it does not work'. Your
description does not even tell us if this is a normal program behaviour
or an error.
> BTW, once the source is available,
The source is available - just not yet packaged for Windows. You can
download the Unix source package and merge it with the 1.1 Windows
source if you want to work on it.

As said i can reproduce this on Windows so no need for a more detailed
description here.
