Hi Cristián, how does one reproduce the crash?_,,,^..^,,,_ (phone)On Nov 14, 2023, at 8:27 AM, Cristián Pérez ***@***.***> wrote:
Hi folks,
First some context:

I'm working on an M1 Pro, macOS 14.1, no Rosetta, fully native.
This was first discovered on Cuis but I reproduced it in Squeak as well.
I'm using the latest release of the VM from this repository while using Cuis. For Squeak I'm using the latest AIO release.

I've tried to disable primitive mixed-arithmetics handling by the two following ways, getting the same results.
Smalltalk vmParameterAt: 48 put: 64
Smalltalk vmParameterAt: 75 put: false
Here is the trace I get when it crashes
