Hi,
sometimes i render a scene which uses Photon-Mapping, POV segfaults when
sortin Photons!
I use Pov 3.5Beta10 Linux
My Computer:
CPU: AMD TB 1200MHz
RAM: 256MB (384MB Swap)
OS: Debian GNU/Linux sid, kernel 2.4.17
I TRyed to track the segfault and ran pov with gdb, it says following:
,-----
| Program received signal SIGSEGV, Segmentation fault.
| swapPhotons (a=562718, b=562593) at photons.cpp:1675
| 1675 photons.cpp: No such file or directory.
| in photons.cpp
`-----
the scene which i wanted to render is not mine and pretty large (for my
uses)...

Can you email me the scene file(s)? Or is that prohibited since it's not
your scene?

It could, but i noticed the bug also in a scene without any CDG or lathe
objects... is it possible, that when i refract phtons for example with a
glass sphere, and behind it is another object which refracts or reflects
photons, that it crashes?

I can confirm this problem, it occurs while sorting photons and only seems
to happen with large numbers of photons. WinPov has no problems with the
same scene file.

But there was a problem like this sometimes ago in WinPov, too. I confirmed
such a problem IIRC. It occured only with large numbers of photons, too.

That did not help, since the thread was not started by me. :-)
I found the thread:
http://news.povray.org/3bb5d946$1@news.povray.org
WinPov doesn't crash anymore with the given scene. At least not in a quick
test.
