#16 Decompiler hangs when a AS3 SWF contains a call to a method that does not exist

If you are looking for the decompiler itself, visit https://github.com/jindrapetrik/jpexs-decompiler

10/01/2017 + update 2020: WARNING - support of the decompiler is now VERY LIMITED. There are no active developers. This means we will NOT develop new features and/or fix most of bugs. We left the tracker running in case somebody from community would like to work on it. Sorry for the inconvenience.

What steps will reproduce the problem? 1. take an swf file and run it through an obfuscator that has protection based on adding a call to a nonexistent method. 2. open the swf in flash player... no crash of flash player, it just ignores the function. 3. open the swf in ASDEC and the decompiler hangs. What is the expected output? What do you see instead? It should skip over the nonexistant function. Instead it hangs while looking for the function. What version of the product are you using? On what operating system? beta 1

Hi, could you please be more specific? What AVM instruction does this? Could you provide sample SWF file? (email)

Same here. But -all- decompilers (Xilix / JP / SoThink) are freezing. File: http://www.mp3cutter.in/extracter.swf Everything works fine, until it tries to decompile a small empty function.

It looks too occur when hitting a long list of functions, finally. I don't know a lot about SWF, but I posted the link to the file I've tried to decompile in my last message.

leon.pelletier: Use version 1.3.1, the file should decompile. It takes more time on one of the scripts, because the script is very long, but after the long waiting, it will decompile :-). thehairyrock: I cannot reproduce this without having sample SWF or know which instruction does this, so I am going to close this issue with cannot reproduce..
