I have found what the problem is. I simply neglected to make a
conservative assumption about suffix truncation needing to add a heap
TID to a leaf page's new high key in nbtsort.c (following commit
dd299df8189), even though I didn't make the same mistake in
nbtsplitloc.c. Not sure how I managed to make such a basic error.

Andreas' test case works fine with the attached patch. I won't push a
fix for this today.
