Hello, I'm on a ARM64 MacOS machine and updated from 0.5.12 to 0.5.13
via Macports only to get a very strange failure (nothing printed)
attached as a script. I then tried on
5139d6a27763fc0be386e15634db21e45598b299 ("shell: Fix unsigned char
promotion and truncation") since my problem seemed similar but not
cigar; tried using a modern clang (21) instead of the system one too.

Hope GMail doesn't botch anything (nothing else at work).
