See, this is why reporting the _actual_ code which causes an error
helps; or, if you want to simplify, at least test that the failure still
happens with the simplified version.

This was a bug, fixed on 2010-10-10 and the fix included in the release
of zsh 4.3.11.  The current version of zsh is 4.3.12.  Negated patterns
and tests combined with &&/|| failed prior to that when using the =~
operator.

If you are running 4.3.11 or newer, please state which version you're
using and preferably show the minimum needed to reproduce, starting from
"zsh -f".
