I can't reproduce this anymore after commit b270713fd.  I think it's
probably the same thing I found while making a test for your other
report:

    logicalrep_partition_open() failed to ensure that the
    LogicalRepPartMapEntry it built for a partition was fully
    independent of that for the partition root, leading to
    trouble if the root entry was later freed or rebuilt.

My failure to see a crash on HEAD was probably an accidental
issue of memory reuse patterns.
