No, it doesn't.  I ran «lldb /srv/zsh/bin/zsh» and typed «r» to launch
zsh, and trimmed that part of the output before posting.  I also trimmed
the value of $abs_srcdir and a few other things.

And in any case, the message above is a DPUTS(); it has nothing to do
with whether zsh was run under a debugger or not.

Although, come to think of it, I'm not sure where that "16:" at the
start of the line is from.

P.S.  Double digression: How do I invoke lldb in a way that'll cause it
to run the target automatically?  I'm looking for something along the
lines of «lldb --foo r -- /path/to/zsh», where «r» is the lldb command
for starting the target.  I've tried -o and -s and they do start zsh,
but the tty settings are wrong (^D doesn't work, for example).
