That would be great, thanks! I had a typo in the instructions above,
CONTAINER_BASE is not supposed to have @sha256:fa35adeae1a at the end.
I tried to debug this by importing _emergency_putc from the kernel and
seeing where it's getting stuck. I tried on the working case (GCC13) and
calling _emergency_putc before _start doesn't work. Unfortunately, that's
where it hangs (or maybe, code isn't executed at all?) for GCC14 so that
didn't help me narrow down the issue.
Cheers,
Ahmad
