There are also various hacks that are compiled into Debian's version

At this moment, I'm kind of leaning toward one of those hacks being
triggered by your specific combination of factors.
That's the most convincing conjecture so far, I'd say :)
It's bash:
$ bash -uc :
$ ( bash -uc : )
'PS1='
/etc/bash.bashrc: line 8: PS1: unbound variable
$ ( bash -uc : ; : )
$
I modified /etc/bash.bashrc to prove it was only being sourced in the
second case above (it prints the value of PS1)
And now I can reproduce without -u
$ bash -c :
$ ( bash -c : )
'PS1='
$ ( bash -c : ; : )
$
