[Pharo-project] Crashes: Pharo 1.3 + Cog VM 13307

Hi, I have been running Pharo 1.3 (#13315) with a pre-built Cog VM's downloaded from Eliot's site in a reliable manner (i.e. very few crashes) for many months. Just last week, I decided to try the Cog VM that is served from the Pharo website (Cog VM Mac-13307) and I am experiencing continuous crashes of the image. I am attaching a dump to this email. Once I switched back to the latest VM served on Eliot's site (VM.r2522), I stopped experiencing these crashes. If I experience this, probably other are too… cheers, Johan
