It almost looks like the function gets replaced with random memory.
`functions TRAPINT` just shows random bytes, for example:

$ xxd <(functions TRAPINT)
00000000: 5452 4150 494e 5420 2829 207b 0a09 0701  TRAPINT () {....
00000010: 200a 0950 200a 7d0a                       ..P .}.


I am now more convinced it's a bug in Zsh. Any advice on how to debug this?
And where can I best submit a bug report to?
