We have a largish codebase and use the -minify flag when building for production.
Since v6 this has been broken though, as methods with the name ‘call’ get removed, as well as any references to these methods.
I have tried with Lime 5.6.0 & 5.9.1, both exhibit the same behaviour.
Also, I think might be the root cause of this issue:
Can you tell if adding DCE does it, or if it’s Google Closure? You can try openfl test html5 --dce full and see if it’s dead-code elimination, otherwise it’s during the minification process
EDIT: I guess you said -minify, not -final, so it would be Closure. We did update Closure to a newer version. You could try and see if a different version works better by swapping our version with another?
