Thanks Frank.
I tried again (more awake) and I was able to solve the problem. In Pharo, the TestSuite has a mechanism to nuke all the instance vars of the test classes during tearDown. That's the reason why this cropped up in Squeak. The solution was to write our own little helper for that:
tearDownInstanceVariables
self class withAllSuperclasses do: [ :class |
class = TestCase ifTrue: [ ^ self ].
class instVarNames do: [ :varName |
self
instVarNamed: varName
put: nil ] ]
Cheers,
Max
