Hallo to all and a big "Thank you" to the developers :))

Hope this the right place to report this...

Rendering some of the examples I found this:

thh@quadro:~$ cd '/home/thh/POV_Master/share/povray-3.7/scenes/advanced'
thh@quadro:~/POV_Master/share/povray-3.7/scenes/advanced$ povray 
abyss.pov +p -w320 -h120
Persistence of Vision(tm) Ray Tracer Version 
3.7.1-alpha.8463913.unofficial (g++
  4.9.2 @ x86_64-unknown-linux-gnu)
This is an unofficial version compiled by:

Is it just me, my system or... is there really something that needs to 
be changed?

I would be happy to provide additional informations if necessary.

No... I'm not a native speaker.

Well, on my system, the render just crashed POV-Ray (v3.71).

Thank you for looking into it Thomas.

So it seems it's not just me ;)

This is what I found following the hint Thomas gave :)

Checking the sub part by part...


After adding the following snippet, I get the error decribed above:

//--------------------------------------------
// Bottom
//--------------------------------------------
#declare HalfSubBottom=union{
          difference{
                 object{Part1} // bottom front
                 plane{y,0 inverse}
                 plane{z,0 inverse}
                 plane{x,0 inverse}
                 scale <SX,SYbot,SZfront>
         }
         difference{
                 object{Part3} // bottom rear
                 plane{y,0 inverse}
                 plane{z,0}
                 plane{x,0 inverse}
                 scale <SX,SYbot,SZrear>
         }
}

The result here:

*** Error in `povray': double free or corruption (out): 
0x00007f8f200efc30 ***
Abgebrochen

Hope this helps tracking down the error :)

Additional information: Comment out the first difference and the error 
is gone ;)

Again... Hope this helps :)

I can confirm that as a genuine bug.

Please test whether 3.7.1-alpha.8492620 fixes the issue for you.

Thanks for confirming this as a bug clipka :)

Unfortunately I have to leave home in a few minutes...

I will try it in a few hours and report back here :)

I tried it with top of master branch (git id:
9762bc5aeb6a63aca87f1523ec7e760030b46341 ), aka
3.7.1-alpha.8492620.unofficial

and no problem on linux 64 bits, whatever the compiler (intel, gnu, clan
g)

cmpovray abyss.pov +p -w320 -h120

Sadly, I cannot test so easily the previous revision anymore... I have
automated the compilation and installation of both official branches
(as well as mine :P )

On the smiling side: no problem either with the stable branch.

Yes, sure, you are VERY RIGHT to report any bug here to CLipka. Trust
me, you do us a big favor. Thanks for helping us to improve POV-Ray. The
more bugs can be found, the better. We need a functioning POV-Ray.

Not only me, but also CLipka is thankful for your help.
:-)

Well, as a matter of fact he is -- provided the reports are indeed about
bugs, and not about something you entirely misunderstood or stuff like
that ;)
