Hello. I'm seeing this runtime crash. Anyone seen this before?

Thread 1: EXC_BAD_ACCESS (code=1, address=0x0)

I'm using compose-multiplatform 1.4 w/ kotlin 1.8.20, reproducer here

Doesn't looks like it is crashing with kotlin 1.8.21, so this workaround works for now

// TODO: Remove once a compiler with support for >1.8.21 available
compose {
  kotlinCompilerPlugin.set(dependencies.compiler.forKotlin("1.8.20"))
  kotlinCompilerPluginArgs.add("suppressKotlinVersionCompatibilityCheck=1.8.21")
}

That's going to be a missed null pointer. I've seen this before with odd constructor ordering.

We have reproduced the issue and found the root cause (unfortunately the bug still persists in Kotlin 1.8.21 and is not reproduced by a lucky coincidence)

Is there an issue for this on the issue tracker? Also, I didn't run into this once I bumped to 1.8.21 but I mightve been extremely lucky

Yes, the issue is here: https://youtrack.jetbrains.com/issue/KT-58441/Kotlin-Native-ObjCAction-ObjCOutlet-generate-bridges-without-switching-state You may check periodically its status
