Follow-up promised after my remarks about quality of Megapov 1.2.1 release.

Problem: Megapov 1.2.1 as compiled by Christoph (binary download) or
compiled by myself (source download) using the default ./configure
settings, crashes and/or hangs my Athlon XP with Gentoo Linux 2.6.12.

Which scene ?
Halfway through projection.pov  and at approx 75% of the cube animation.

Its your hardware !!!!
No. Booted into memtest86+, let it run for a night, no problems.
Booted into XP (yes I have to admit, I still have a XP partition)
downloaded Megapov 1.2.1 for Win. All scenes rendered ok.

It's your kernel/glibc etc. !!
No. Got a free Suse 9.3 disk from a magazin, installed on free
partition: same errors. Installed new Gentoo 2005.1 release: same errors.

You run a patched version.
No. Downloaded stock versions of PovRay 3.6.1. and Megapov 1.2.1,
installed on empty partition and compiled using default settings.

Any progress ?
Yes. Recompiled with: ./configure --disable-optimiz  Slow as turtle, but
completed the scenes. Added, one-by-one, "O1" "-march=athlon-xp" "02"
"-fomit-frame-pointer" and finaly "O3" and "-ffast-math". I am currently
enjoying a stable version !!

Configured with:
./configure COMPILED_BY="Willem" --disable-optimiz
CXXFLAGS="-march=athlon-xp -ffast-math -O3 -fomit-frame-pointer -pipe"
CFLAGS="-O3 -march=athlon-xp -ffast-math -fomit-frame-pointer -pipe"

Anyone else using the unix version ??
