Hi, This is indeed strange, the BlockClosure has an incorrect startpc (31 instead of 43). You can fix it with: theBlock instVar: 2 put: 43. The wrong startpc corresponds to the beginning of the block in the previous version of the method (DFSession>>#numberOfMethodCalls), but I don't know why. I don't know fuel enough but could it be because the method of the block changed between serialization and materialization?
