Interesting! Is this any app, or just a particular one? I'm wondering if there's a particular function that it's struggling to AOT-compile...

We shouldn't have changed anything in the compile-abc utility but we can double-check..

[Oldes]

I have the same crash when using AIR 32.0.0.166 ... any idea why?

[Oldes]

Maybe I have wrong version of clang?

Apple clang version 11.0.0 (clang-1100.0.33.8)
Target: x86_64-apple-darwin18.7.0
Thread model: posix

[Oldes]

hm... it looks that our older app is still packing correctly with the air 32.0.0.166, so it is something related to the new one.. especially when there are no other people complaining

[Oldes]

When I use SWF from the old app in the new one, it is compiling without issue.. so it will be long hunt to find out, what is different in the new app. :-(

[ajwfrost]

So this is something related to a change in the ActionScript? Must be some specific format that's causing a problem .. which sounded familiar: can you please check the below link https://github.com/Gamua/Adobe-Runtime-Support/issues/281#issuecomment-605852694

There's an empty switch case which appears to be causing a problem..?

thanks

[Oldes]

I don't know what happend, but after messing around, without actually changing any code in AS yet, it starts packing... strange. Maybe it is because I changed file permissions.. don't now... I'm not able to reproduce the crash anymore.

[Oldes]

I'm closing it, as I'm not able to reproduce the issue anymore :/ don't know, why it was there, but it is gone.
