Thank you for the report and the supplied dump with the reproduction. I can confirm that the NPE is also present on HEAD, and I will look into it.

Quite a few of the class files in the dump has malformed inner-class attribute, where R8 reports e.g.:

Info in /tmp/tmpo67ucguh/program.jar:ofifmwrrhhmodsc/ψξψξψξξ.class:
Malformed inner-class attribute:
	outerTypeInternal: ofifmwrrhhmodsc/ψξψξψξξ
	innerTypeInternal: ofifmwrrhhmodsc/ψξψξψξξ$ψξξψξξξ
	innerName: ψξψξψξξ$ψξξψξξξ

These are ignored, so they should not be the reason for the NPE, but something to also look into.
