Buildfarm member skink has been unhappy since this patch went in.
Running the regression tests under valgrind easily reproduces the
failure. Now, I might be wrong about which of the patches committed
on Friday caused the unhappiness, but the valgrind backtrace sure
looks like it's to do with partition routing:

(This is my local result, but skink's log looks about the same.)
