Thank you for the report. This looks looks like something in the class file that our class file verification cannot handle. The failing_bytecode.txt does not have all the details, so will it be possible for you to share the binary class file for the class kbbbbb.kggkkk? You can share it privately with javap with the -v option (javap -v -cp <the jar> kbbbbb.kggkkk.
The deobfuscated R8 stack trace is:

Sent over the class file via email, thanks!

Thank you for the file - was able to reproduce it and have a fix ready. Will report back when the fix has been backported to 2.2
Description
When retrace is invoked with just the mapping file (one arg) it looks like it is hanging, if you don't know that it expects a stack trace on stdio. When reading from a terminal we could write a message to clarify that, e.g. "Awaiting stack trace on stdin, press Ctrl-D to retrace".
