After stepping through the test program in a debugger, I see that mdb_page_search returns MDB_NOTFOUND if mc->mc_db->md_root is P_INVALID because the tree is empty. And mdb_cursor_put sets rc to MDB_NO_ROOT if mc->mc_db->md_root is P_INVALID.
So that can't be related to the crash, at least not in the instances I'm investigating, because insert_key and insert_data (and hence rc) is always MDB_NOTFOUND in their minidumps when the crash occurs, which can't happen when rc is set to MDB_NO_ROOT.
