bug with completion (after 15 oct?)



Heyla,
am currently investigating a bug with completion which manifested in the
last week or so:

% zsh.new -f
% cd /tmp; mkdir foo; cd foo; touch bar baz
% ls ba<TAB>	# <TAB><RETURN> or CTRL-U or whatever
bar baz
% ls ba<TAB>	# OK
% exit
% zsh.new
% cd /tmp
% ls ba<TAB>	# <TAB><RETURN> or CTRL-U or whatever
--> completing file
bar   baz
% ls ba<TAB>
zsh: 20301 segmentation fault (core dumped)  zsh.new

A backtrace gives the following - maybe it's useful to someone - but I'll
try to narrow it down to a set of initialisation options.
Hmm, what's worse is that a version compiled --disable-dynamic sometimes
gives a segv a bit later (line 1034).
