Does anyone here feel like helping out with a FTBFS in synfigstudio due
to a floating point exception in synfig on alpha? If someone could get a
backtrace, or a patch or other hint, that would be great.
Steps to reproduce:
sudo aptitude install synfig synfig-dbg
mkdir tmp ; cd tmp
wget http://svn.voria.com/code/synfig-studio/trunk/images/installer_logo.sif
wget http://svn.voria.com/code/synfig-studio/trunk/images/logo.sif
synfig -q installer_logo.sif -o installer_logo.png --time 0
gdb synfig
run -q installer_logo.sif -o installer_logo.png --time 0

So looking at the build log for synfig on alpha, I see:
checking for optimization flags... -O2 -ffast-math
and this is what -ffast-math does on alpha. :)
