Subject: synfig: crashes on alpha, m68k, mipsel, powerpc

Date: Sat, 13 May 2006 12:10:08 +0800

[Message part 1 (text/plain, inline)]

Package: synfig
Version: 0.61.05-4
Severity: serious

As can be seen from [1], synfig doesn't work on several RC platforms.

     1. http://buildd.debian.org/~jeroen/status/package.php?p=synfigstudio

This bug is primarily to keep synfig out of etch (once it is removed)
and track the issue for people on those platforms noticing the bug.

Got a similar report upstream, now I understand that this is 3 separate
issues - using lots of memory (causing the OOM killer to kick in), a
floating point exception on alpha and a really weird segfault on m68k,
which looks similar to what some users have reported upstream before
with a broken C++ compiler.

Subject: synfig: 367048: can anyone help with a floating point exception?

[Message part 1 (text/plain, inline)]

Hi all,

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
bt

Please CC 367048@bugs.debian.org in replies.

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. :)
