JPEXS Free Flash Decompiler Issue Tracker

> What steps will reproduce the problem? I found that when using the new version ffdec_20.1.0, some methods in the scripts cannot be decompiled. However, when using versions ffdec_18.5.0 and ffdec_19.0.0, these methods can be decompiled normally. An example method name is: public function zysjgood. I have uploaded the SWF file. This method is in the maintimeline script. > What is the expected output? What do you see instead? After attempting to decompile the method, it resulted in an IndexOutOfBoundsException with the message "Index -2 out of bounds for length 6." > What version of the product are you using? Is it "nightly build"? Which operating system do you have? The version is ffdec_20.1.0, and it's not a "nightly build" version. I'm using the Windows 10 operating system. I believe the issue is not related to the system. > Please provide any additional information below. If the problem is related to a SWF file, attach it here, otherwise we can't help you. I have attached the SWF file.The method is located in the maintimeline script of the SWF file. Reproducing the issue only requires decompiling the maintimeline script of the SWF file to see the result.
