[squeak-dev] [BUG] Compiler Bug: Code generation with cascade and #caseOf: fails

Steps to reproduce:

Do it:

Object compile: '

foo: anObject

^ self foo

    flag: #bar;

    caseOf: { [#corge] -> [self grault: anObject] }



In TempVariableNode >> #isReferencedWithinBlockExtent:: MessageNotUnderstood: UndefinedObject >> #rangleIncludes:.

anInterval is nil.

In #computeCopiedValues:, blockExtent of the BlockNode {[#corge]} is nil.

This may be related to the observation made in http://forum.world.st/BUG-Cannot-compile-cascade-sent-to-block-td5108942.html that blockExtent can be nil.

Maybe we should handle optimized BlockNodes differently in this method?

Not (yet?) further investigated.
