zsh function .zwc parse errors

After installing, I get errors every time I open a new iTerm window:

/Users/bengolder/.zsh/functions/_git_delete_branch.zwc:1: parse error near `)'
/Users/bengolder/.zsh/functions/change-extension.zwc:1: no such file or directory: ^G^F^E^D^A^H^A

It's clear that these are occurring when the zshrc file runs this loop to source all the files in .zsh/functions:

# load custom executable functions
for function in ~/.zsh/functions/*; do
  source $function
done

If I delete the ~/.zsh directory and rerun rcup, the errors are absent until new .zwc files are autogenerated for each file in ~/.zsh/functions:

Wed Apr 24 10:49 AM functions % pwd
/Users/bengolder/.zsh/functions

• iTerm2 3.4.23
• zsh 5.9 (arm-apple-darwin23.0.0), installed via homebrew

Any questions or debugging suggestions welcome!

Start with the zshrc loop that sources every entry under ~/.zsh/functions, then reproduce the issue by opening a new shell after rcup generates the .zwc files. Check how the loop handles compiled files alongside the symlinked functions. Done means new shells start without parse or command errors while the custom functions remain available.
