Expect to see the Decompiled Script
Instead FFDEC V4.0.1 HANGS.....
(USES OVER A GB OF RAM AND HOGS THE CPU AND JUST HANGS THERE)
> What version of the product are you using? On what operating system?
V 4.0.1 ON WIN 8.1 64 BIT

IF TRYING TO EXPORT THE 'scripts' folder it works without a problem until it gets to
'scripts\com\adobe\utils\DateUtil.as' then it just hangs indefinitely, hogging over 1 GB
of RAM AND UP TO 90% OF cpu UNTIL TERMINATED BY THE 'TASK MANAGER'! It cannot be
terminated any other way once it starts to hang!
FFDEC VERSION 4.04 PRODUCES EXACTLY THE SAME RESULT!
Please attach your swf file. Are you sure that it is not obfuscated? I dont think that
this is a serious bug...
You are right lines 62-71 read:
public static function toRFC822(param1:Date) : String
{
/*
* Decompilation error
* Code may be obfuscated
* Tip: You can try enabling "Automatic deobfucation" in Settings
* Error type: TranslateException
*/
throw new flash.errors.IllegalOperationError("Not decompiled due to error");
}
I tried using Automatic Deobfuscation but it didn't help.
Surely thedecompiler can get past that though?
In fact there are 5 Decompilation errors in the code.
Without the swf file we can't help you, sorry.
You can try to set the timeouts in advanced settigns, but it will solve only the "just
hangs indefinitely" problem, it wont help you to decomile your script.
Timeouts don't seem to have any affect whatsoever. When it hangs it hangs because it is
dead!

Sorry, but the information you attached it not useful for us. We can't fix your problem
without the swf file.
Can you still reproduce the problem with the latest nightly build?
Same problem for me, it crashes in some 100.000+ lines files. The one i was trying to
decompile was 115.857 lines of code, and it got froze.
This is V4.0.5.
The problem is that decompiler crashes when decompiling 10.000+ lines at same time. There
should be a ANTI-CPU-LAG thingy (we could make it optional, as 100 lines per sec as
default).
realmaster42: Is the problem with EERS.swf? which class?
The original com.adobe.utils.DateUtil can be decompiled. (I've attached it)
You file if obfuscated, read this info about obfuscated swfs:

(And we still can't fix your problem without the SWF file)

Since you did not attach any swf file, I am closing this issue as invalid.
