> What steps will reproduce the problem?
I'm decompiling some very similar classes. They describe some protocol data, and have
methods to put those data in to binary stream, and read it back. Originally CASE
startement used in read method to read data. If I have about 20 cases than decompiller
return nice looking case startement, but if case count about 30-40 then it fail decompile
in CASE and produce IF ELSE series.
I will provide examples of decompilled code and corresponding AVM2 code.

> What steps will reproduce the problem?
I'm decompiling some very similar classes. They describe some protocol data, and have
methods to put those data in to binary stream, and read it back. Originally CASE
startement used in read method to read data. If I have about 20 cases than decompiller
return nice looking case startement, but if case count about 30-40 then it fail decompile
in CASE and produce IF ELSE series.
I will provide examples of decompilled code and corresponding AVM2 code.
They are in attached files
> What is the expected output? What do you see instead?
I expect correctly decomiled CASE startements.
I see IF ELSE instead.
> What version of the product are you using? Is it "nightly build"? Which operating system
do you have?
JPEXS FreeFlash Decompiler v.6.0.1
> Please provide any additional information below. If the problem is related to a SWF
file, attach it here, otherwise we can't help you.
Before V6 JPEXS FreeFlash Decompiler all those decomiled as IF ELSE, also on BIG amount of
CASE branches decompilation failed.
Also I noticed that decompiling classes with those case startements take than decompiler
failed to produce CASE take very long time.
correct_case_decomilation.as (7 KiB)correct_case_decomilation.avm2 (13 KiB)failed_case_decomilation.as (29 KiB)failed_case_decomilation.avm2 (26 KiB)
I am sorry for letting you wait so much without an answer and I don't think it is now
(after flash shutdown) even relevant, but
I cannot reproduce it in current version, it seems to be fixed, so I am closing this
issue.
