Just for the record, I didn't ask for permission to debug this -- I asked
whether posting the (IMO) relevant parts of the strace output would be
helpful to others in debugging this.  I also asked for advice in debugging
the code...  I won't have much time to work on this until later next week,
so some analysis of the failing strace output is as much as I can provide
at the moment.
