Detekt 1.22.0-RC1 -> 1.22.0-RC2 breaks UnreachableCode

[jeffdcamp]

After updating from Detekt 1.22.0-RC1 to 1.22.0-RC2 invalid UnreachableCode violations are showing

Expected Behavior

Code called from external libraries should not cause UnreachableCode

Observed Behavior

Any code called from an external library in an ?: operator causes UnreachableCode

Steps to Reproduce

Run ./gradlew detektDebug

Error:
Test.kt:13:9: This expression is unreachable code which should either be used or removed. [UnreachableCode]

Sample Code (Failing code on line 11, Workaround code on line 12)

package org.test

import androidx.core.net.toUri

class Test {
    fun testBug() {
        getLastPathSegment("test.mp4")
    }

    private fun getLastPathSegment(uriText: String) {
        val uri = uriText.toUri() // causes UnreachableCode.... code ref in core-ktx-1.5.0.jar: public inline fun String.toUri(): Uri = Uri.parse(this))
//        val uri = Uri.parse(uriText) // does NOT cause UnreachableCode (copied code from core-ktx-1.5.0.jar)
        val lastPath = uri.lastPathSegment ?: return
        println(lastPath)
    }
}

Your Environment

Detekt 1.2.2.0-RC2
Seen this same issue in many projects on different dev environments

I have two theories here:

• We updated the kotlin compiler that we use under the hood so, maybe, that broke this
• This is related with Detekt 1.22.0-RC1 -> 1.22.0-RC2 breaks ignoreAnnotated #5427
