Stopping during parsing seems to crash for me. If nobody can reproduce it, I
take it it's time for a re-install for me :) Anyway, here's my report:

I write this into a new scene, and save it:

#while(1)
#debug "X\n"
#end

Then I let it parse for a few second, and hit Stop.
Now I hit Run again.

After printing the standard message, but before printing the first X, I get
this:

PVENGINE caused an invalid page fault in modul PVENGINE.EXE at 0177:00480443.

Sometimes it starts parsing again, but when I do Stop/Run another time, I
get the above crash.

The exact same thing happens to me when I do as
Elias describes below.

But I haven't tried it in the official v3.5 beta
release yet. Only in the latest (I think) pre-beta
release for Windows.


I'm running Windows 98 on a 100MHz Pentium with
32MB RAM.

Btw.: Here's the error message:

"This program has performed an illegal operation
and will be shut down..."

(Note that POV seems to be "alive" behind this error
message until I chose Close in the error window.)

The bug appears as described above except that it is consistently after the
second restart.  It does not occur for stopping parsing/restarting in
general for me (ie. I ran some scripts that take a long time to parse and
stopped/restarted them several times with no crashes).
Here is the stack dump for one of my runs.

I can't get it to happen reliably like you can, but I can confirm that a crash is
possible. I will look into it.

 It's "#debug" for sure... only happens with this directive, and doesn't
needs the #while loop to crash. Put a lot (a big lot) of lines containing
'#debug ""' and it will happen if you click start/stop fast enough. Oh! And
it doesn't happens on official 3.1!

Put down that Windows ME CD.  It happened to me, too.

I'm running POV 3.5b1 on a Pentium II 400MHz with 256MB RAM and Windows 2000
Professional with Service Pack 2.

It takes me quite a few tries to reproduce it (around 14 for the first time
I did it), but it still happens.  I've found that the crash can be bypassed
by a program such as CrashProof, and POV will still work fine afterwards.
