Category: Crasher/nasty bug Group: GIT version Status: Open >Resolution: Accepted Priority: 5 Private: No Submitted By: Mika Laari (mikalaari) Assigned to: Nobody/Anonymous (nobody) Summary: Super sample layer on rotate layer crash with height/width 0 Initial Comment: The passes to reproduce the crash: 1. Create a Rotate layer 2. Create a Super Sample layer above the Rotate layer 3. Move the origo of the Rotate layer (couple of dozens each) 4. Rotate the Rotate layer (i.e. change the Amount parameter) about 30 degrees for example 5. Set the Width or the Height parameter of the Super Sample layer to 0 (zero) 6. The program crashes Sometimes I have to modify the parameters of the Rotate layer and then set the Width or Height of Super Sample to zero again to make Synfig crash. Sometimes one of Width or Height does not trigger the bug but the other does. I have compiled the binaries myself on Ubuntu 10.10 using an AMD Athlon II X2 250. Here are the contents of Synfig's About dialog. Synfig Studio 0.62.02 2D vector animation studio Development version: Revision: 20101113 Branch: master Revision ID: 961d8b Built on Nov 22 2010 Built with: ETL 0.04.13 Synfig API (006000) Synfig library 47 GTK+ 2.22.0 GNU G++ 4.4.5 Using: Synfig 0.62.02 GTK+ 2.22.0 Now the backtrace of a crash: Program received signal SIGSEGV, Segmentation fault.

Maybe it's a problem in my version, but in that case someone could verify if it can be reproduced by others. ---------------------------------------------------------------------- >Comment By: Genete (genete) Date: 2011-06-26 18:19 Message: Reproducible on 0.63.00. I can make it hang but not crash. Anyway, what does mean supersample with x and/or y sizes set to zero? I see all the context disappear. I think that it doesn't have sense to allow supersample sets its values to 0 or negative. ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=757416&aid=3147736&group_id=144022 ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable.
