That sounds like you have a binfmt that accepts crap. Possibly
ARM-specific, although more likely it's just a misc script.

Well, it wouldn't be trinity any more, it would likely be some execve
script (think "/bin/sh", except likely through binfmt_misc).

Do you have anything in /proc/sys/fs/binfmt_misc? I don't see anything
else that would trigger it.

This doesn't really look anything like DaveJ's issue, but who knows..
