No, just plain 'zsh'.  I'm running my standard setup, not sure what 
details are relevant.  compinit yes, as always.

styles:

--------------------------------------------------------------------------------------------------------

zstyle ':completion:*:default' list-colors ${(s.:.)LS_COLORS}

Correct, but 291 'newlines' and then crashes, whereas 274 (tho I have to 
press TAB twice to get past the 'zsh' which is just a link to the 
current binary) stays on the same line and then completes without 
trouble. One sees the list of possible completions, and all is as it 
should be.

Ok.

I'm actually using 'xfce4-terminal' which seems not to have the '-hold' 
ability.  Starting that from within itself the results are the same, the 
terminal evaporates, leaving the calling terminal. With 'xterm -hold' 
any attempt at completion of anything freezes the xterm solid.  I kill 
it by closing the window. No message. Plain 'xterm' does the same as 
xfce4-terminal--it evaporates back to the calling terminal.

That's new territory for me, so I'll need a primer.

293 is the same as 291.

274 is still perfect.

Everything is fine with 'zsh -f' (with 293). So then this is something 
specific to my configuration?  Should I narrow it down by elimination?
