I can confirm that. The FilePlugin is unhappy to receive such integers as
file position. The same is true for primitive 71 (#basicNew:) which
sometimes signals OutOfMemory error for such arguments.
I managed to create a broken .mcz with the VM, without getting any errors.
SourceFiles second readOnlyCopy position: (LargePositiveInteger new: 4).
ByteArray basicNew: (LargePositiveInteger new: 1). "==> OutOfMemory"
ByteArray basicNew: (LargePositiveInteger new: 4). "==> #"
