I think that is related with interrupt processing or something. or a buffer overflow.

Try using make run, I used make run and didn't find any issues while using vim.

It happens to me when using the \ key.
One think that might be worth mentioning is that my layout is not US, so the key should be \ in the US layout.

[FrostyTheSouthernSnowman]

\ also didn't give me any problems. I used the make run command. What command did you use, @R4V10L1?

[8dcc]

I just installed the ISO.

[FrostyTheSouthernSnowman]

Ok. I used make to build it from source and then ran it with make run. I wonder if the ISO you downloaded was built using make distro which adds some extra features.

[FrostyTheSouthernSnowman]

I will try to test it with the make distro command.

[FrostyTheSouthernSnowman]

I downloaded the ISO file and ran the VM using make run and still couldn't find the issue.

[FrostyTheSouthernSnowman]

make distro failed

[mguinhos]

I am also not using the US layout.

My layout is BR ABNT2.

Maybe the error in my screenshot has something to do with trying to access a key in a position that does not exist in the vinix default layout?
For example if some layout has more keys or characters, the \ key might get 'shifted', and vinix tries to access it in a smaller array.

I don't know how vinix handles layouts or keys, and I don't even know if the error is related, just pure speculation 🙂

This seems to be a duplicate of #104.

In any case I cannot reproduce the nano panic by pressing ( or ).
