Hi Tobias,

as the commit comments says, you must first load Compiler-eem.379.  The update steam contains an update for it.  And its commit comment explains the issue:

Name: Compiler-eem.379
Author: eem
Time: 20 March 2018, 3:27:27.12646 pm
UUID: b3856f24-9d98-478a-936f-c6d24d667be4
Ancestors: Compiler-eem.378

Add initialization of the Undeclared variable addedExtraLiterals which is soon to be a replacement for Encoder's addedSelectorAndMethodClassLiterals, a name which is now misleading given the new full block support.  By adding the initialization of the Undeclared variable the compiler is not broken as the instance variable is renamed and Encoder's methods are recompiled.

>>  I encode names and literals into tree nodes with byte codes for the compiler. Byte codes for literals are not assigned until the tree-sizing pass of the compiler, because only then is it known which literals are actually needed. I also keep track of sourceCode ranges during parsing and code generation so I can provide an inverse map for the debugger.!
