JPEXS Free Flash Decompiler Issue Tracker

<b>What steps will reproduce the problem?</b> Decompile an obfuscated file that contains AS1/2 (most typical for secureSWF). <b>What is the expected output? What do you see instead?</b> In some cases (most typical for branches - if, switch) the source code is skewed. Or even an error arise (Try DoInitAction 35 in the attached file). The inspection has shown that there is a problem while deobfuscating functions with a lot of dead code. An internal addressing of the function could exceed the address of the next (after the function) instruction. Action Push register1 &quot;_tf&quot; is at 2104 Action GetMember is at 2111 Action Push &quot;embedFonts&quot; is at 2112 Action GetMember is at 2117 Action Return is at 2118 Action Push &quot;embedFonts&quot; 3 register2 &quot;addProperty&quot; is at 2119 Action CallMethod is at 2133 Action Pop is at 2134 &lt;&lt;&lt; last instruction of the function's body Action SetMember is at 2091 &lt;&lt;&lt; next address after function Action Push 1 null &quot;mx&quot; is at 2092 Action GetVariable is at 2103 Action Push &quot;styles&quot; is at 2104 Action GetMember is at 2109 Action Push &quot;CSSTextStyles&quot; is at 2110 Action GetMember is at 2115 Action Push &quot;prototype&quot; is at 2116 Action GetMember is at 2121 Action Push 3 &quot;ASSetPropFlags&quot; is at 2122 Action CallFunction is at 2132 Action Pop is at 2133 Action Push is at 2134 This often leads to wrong reference definition: GetMember Return } Push &quot;embedFonts&quot; 3 register2 &quot;addProperty&quot; loc0855:CallMethod &lt;&lt;&lt; wrong location, which is actually taken as it occurs first Pop } SetMember Push 1 null &quot;mx&quot; GetVariable Push &quot;styles&quot; GetMember Push &quot;CSSTextStyles&quot; GetMember Push &quot;prototype&quot; GetMember Push 3 &quot;ASSetPropFlags&quot; CallFunction loc0855:Pop &lt;&lt;&lt; right location Nop <b>What version of the product are you using?
