[Cuis-dev] ReferenceStream cannot read Dictionary object written with Squeak (was Re: ReferenceStream restoreFromFile: aFileEntry goes into infinite loop)

[H. Hirzel]

I could identify the change set which causes the problem, it is from last
Wednesday

CoreUpdates\
7580-ReferenceStream-61BitSmallIntegers-fix-JuanVuletich-2025Sep17-08h16m-jmv.001.cs.st

It introduces a new version of #readInteger and writeInteger: in the class
DataStream.
If I undo the change of this change set it works.
