Back-patch commits 9afc6481117d2dd936e752da0424a2b6b05f6459 and b8fbbcf37f22c5e8361da939ad0fc4be18a34ca9. The first of these is really a minor code cleanup to save a few cycles, but it turns out to provide a workaround for the misoptimization problem described in bug #7516. The second commit adds a regression test case. Back-patch the fix to all active branches. The test case only works as far back as 9.0, because it relies on plpgsql which isn't installed by default before that. (I didn't have success modifying it into an all-plperl form that still provoked a crash, though this may just reflect my lack of Perl-fu.)
