I can't reproduce that problem on either Solaris 8 or GNU/Linux 2.2.

What is the output of "make check"?

If "make check" succeeds, please edit tests/Makefile to add a new file
"delete04.sh" to TESTS, put the following into tests/delete04.sh (as
an executable file), and run "make check" again.  This test attempts
to mimic your problem.

#! /bin/sh
# Deleting a large last member was destroying earlier members.
