Any idea how this compiler error happens? Or what it means?
This seems to happen on the JS side.

The root cause java.lang.IllegalStateException was thrown at: org.jetbrains.kotlin.ir.symbols.impl.IrBindableSymbolBase.bind(IrPrivateSymbolBase.kt:75)
IrVariableSymbolImpl is already bound. Signature: null. Owner: VAR name:_ctx type:<unbound IrClassPublicSymbolImpl> [val]: KtProperty:

So, it means that there are two or more variable declarations that use the same variable symbol

Is it happened after a plugin applying?

[Edoardo Luppi]

Thanks Artem! It is very strange tho.
That _ctx is wrapped into its own scope, e.g.:

if (true) {
  val _ctx = ...
  zzz = _ctx
}

Blocks are all like that (exactly like that).

The file that's compiling is 100k lines (around 4 megabytes).
Might be that the compiler breaks with that amount of code, or after a certain amount of nesting?

Is it happened after a plugin applying?

No no

[Edoardo Luppi]

Just verified it happens on the Native side too.

[Artem Kobzar]

It's so weird. It's definitely should be reported, because I have no idea what is going wrong. It's a common situation in case of a custom compiler plugin (people just create an invalid IR, so backend can't work with it) but not for the project with a lot of code.

I have solved by using an outermost var _ctx, getting rid of if (true) { ... }
This is the commit for the code generator template: https://github.com/Strumenta/antlr-kotlin/pull/152/commits/9d8c347cd9482d91637eeec9f302504a2a00638b

And this is the PR I was working on https://github.com/Strumenta/antlr-kotlin/pull/152

It's definitely should be reported

Sounds good, I'll create a ticket anyway.

I've increased the IDE intellisense max file size to 10 megabytes, let's see if the IDE sees something wrong with the code as it was before

[Edoardo Luppi]

IntelliJ freezed, nice

[Edoardo Luppi]

Unfreezed. The IDE doesn't see any errors, so it really looks like a compiler issue.
