When Cinelerra 1.1 + associated utilities are
compiled from sources using GCC 3.1.1 and
recommended CFLAGS, the 16-bit RGBA and
YUVA models do not work properly. When
blending needs to be done between tracks, the
color information seems to be lost, destroying
the composited output. Screenshots are
attached to provide a visual description of the
System setup: AMD Athlon Thunderbird 850,
Gentoo Linux 1.3, GCC 3.1.1, glibc 2.2.5.
Cinelerra compiled with CFLAGS:
-O3 -march=i686 -fmessage-length=0
(The flags -malign-[loops,jumps,functions] were
deprecated in GCC 3.1.1.)
