Building a tree newer than that revision (171e7fa4c1d9 + some local
patches that don't go anywhere near the parser), I get:

% /path/to/installed/zsh -fnv strcatsub


where the final % is in reverse video, but stays there even with -o nopromptsp.

If I remove the -f, it outputs the same junk, but preceded by the
entirety of my .zshenv.  All that goes to stderr.

My configure line:

    ./configure --enable-zsh-debug --with-term-lib=ncursesw --prefix=$HOME/prefix/zsh
    perl -pi -e 's/link=dynamic/link=static/g; if (/link=static/) { s/auto=yes/auto=no/ }' config.modules
