[Pkg-zsh-devel] Bug#871787: zsh: error "defining function based on alias ..."

[Vincent Lefevre]

Package: zsh
Version: 5.4.1-1
Severity: grave
Justification: renders package unusable

There's a major regression, which breaks my startup scripts:

zira% alias foo=bar
zira% foo() { : }
zsh: defining function based on alias `foo'
zsh: parse error near `()'

Well, I'm not sure whether there are other issues or this is a
consequence of the above bug, but completions are alo broken.
For instance, I can no longer complete on the "man" command.
