For the record, after some off-list traffic this turned out to be the 
case: it's another instance of the glibc-namelookup-in-chroot crash. 
Creating a lib directory inside the chroot (or in the case "lib64" 
worked around the problem).

The underlying bug in glibc has apparently been fixed at some point.

     Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
