Hi Jurai,

   indeed, https://github.com/OpenSmalltalk/opensmalltalk-vm/issues/444 looks To me to be related.  (Apologies got the link formatting; I’m on my phone).

Can you (or soneone in the Pharo team) please
- verify which release Pharo images are valid or invalid
- remove urgently images that are invalid
- contact all potential users asking them to discard the gorrupted images and any derivatives
- close all opensmalltalk-vm issues that are in fact not VM/GC bugs but derivatives of the image corruption

This is a matter of urgency.

I shall try and write a VMMaker and/or VM level script/executable that simply performs the leak check and answers if an image is corrupt or not.  This does not need much of the vm; it only needs the GC, leak checker and image loading components and can be headless.  I’ll discuss this on opensmalltalk-vm and cc Pharo-dev, Squeak-dev & Cuis-dev.
