Hi Marina,
FYI I saw a repeatable crash in the contrib regression tests when
running make check-world with this patch applied.
test hstore_plperl ... FAILED (test process exited with exit code 2)
test hstore_plperlu ... FAILED (test process exited with exit code 2)
test create_transform ... FAILED
I'm not sure why it passes for you but fails here, but we can see from
the backtrace[1] that ExecInitExprRec is receiving a null node pointer
on this Ubuntu Trusty GCC 4.8 amd64 system.
