With the three patches applied I can reproduce the following segfault.
The idea is to make a completion (here on filenames, after cat)
just before completing for $functions (it look like it will
hang only when completing the varname `$functions').

% zsh -f
phobos% autoload -U compinit; compinit
phobos% cat <TAB>
foo.tar.gz   foo.tgz      foobar/
phobos% echo $funct<TAB>
zsh: segmentation fault (core dumped)  zsh -f
