Hi, I was playing around with compiler api on new js IR backend and it seems like declarations from current module get duplicated if I try to reference them in the linker. E.g. if I have class

in my module and I used

IrPluginContext.referenceClass(FqName("A"))

in my extension, I get the following exception (in thread):

Comparing instances of those classes in debugger, they indeed different.

Also worth noting that it fails only on JS backend, JVM works fine

Hi. Is that declaration some kind of special? I mean it’s not defined in sources.

It works for jvm because of at this time jvm doesn’t use Klibs when js/native do.

The basic idea of those API is to reference declaration from external dependency modules

Nope, that declaration is not special and not modified during compilation. It is just an instance passed as a param, and I used

referenceClass

to generate calls to it. Workaround I found is to first check top level declarations in module fragment and only then go through pluginContext. Not ideal, but it works :) Is that intended behaviour tho, oh should I report a bug?

I think at least it worth to be listed in YT so please file an issue.
