+
+If you remove the option `--quickcheck-replay=258328`, the test usually passes.
+
+By the way, if this bug report looks similar to the one I filed in commit 145c343b4 some 9 months back, indeed it is.
+I usually disregard these occasional test failures by simply running the tests again because that seems the
+path of least resistance. However, I just filed a simple compilation issue + patch today[^1], so I thought this would
+be a reasonable thing to do with the same effort involved.
