[Swftools-common] New info -- Was: Problems with avi2swf

[Amartyo Banerjee]

Ok, here is some more info. Perhaps it will help to track down why the segfault 
happens.
My version of avifile as reported by  'avifile-config --version'  is 0.7.39. 
Basically it is a cvs
version, checked out on October 10, 2003.
The avi file was created with ffmpeg using the command listed in my last email 
to this mailing
list about combining jpegs into an swf file.
I recompiled avi2swf with the '-g3' flag. Here is the gdb session:

Hope this helps in figuring out the problem.
