In the attached statistics file you find where this allocation overflowed

Alloc-pool Kind        Pools  Allocated      Peak        Leak
-------------------------------------------------------------
df_scan_ref pool         868 -1403330584  607042176          0

which is similar to what happens in 26854, so perhaps this PR could also be
improved with factored use-def chains.
