--- Comment #1 from Jamie Gritton <jamie@FreeBSD.org> ---
Without yet trying to duplicate anything, I see a possibility: PAM.  The
difference between "ls" and "ls -l" is the latter looks up users.  The
difference between "jexec" and "jexec -U root" is that the former (the defa=
ult)
looks up users inside the jail.  So it seems at first glance that looking u=
p a
user gives you a bad system call.

While your libraries are necessarily all the same, your configurations may =
not
be.  Is it possible that the PAM config on b3 is calling some library that =
b1
isn't?
