Hi,

while I was working with Nile (a new stream library) the VM crashed.

You can reproduce it very easily. Download a fresh 3.9-7067, install Nile-All from monticello (http://www.squeaksource.com/Nile/).

Perhaps a method still accesses an iVar which has gone away, can you do something like

Smalltalk allClassesAndTraits do: [:classOrTrait | ('Nile-*' match: classOrTrait category) ifTrue: [classOrTrait compileAll]] displayingProgress: 'Recompiling Nile classes and traits'.

In a workspace, execute: "NSBenchmarks new benchStringNextPutAllString"

Did not crash after the above recompile, instead it prints 185.1335988978503->167.2261709346418

/Klaus

Then, you get:

sweep failed to find exact end of memory
