title: Android studio, strange error while building kotlin: wrong code generated
body: <p>I'm trying for a few days to build my android project (contains mostly kotlin)...
  I tried to change versions for everything, and I keep getting the same error while building!</p>
  
  <p>The message I'm getting looks like this:</p>
  
  <p>Kotlin Compiler:</p>
  
  <pre><code>org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: wrong code generated
  </code></pre>
  
  <p>Java Compiler:</p>
  
  <pre><code>org.jetbrains.kotlin.codegen.CompilationException: Back-end (JVM) Internal error: Couldn't transform method node:
  
  java.lang.IllegalArgumentException
  </code></pre>
  
  <p>I didn't do any dramatic change that could cause it to happen...
  I tried to rebuild, clean, delete everything, change versions for everything, but I still can't get rid of that.</p>
  
  <p>How can I solve this? </p>
  
  <p>Thanks!</p>
