Best regards, Alexander
I investigated this issue under Valgrind and found that in v13 it is no longer detected and the patch in the discussion above is no longer needed.
But I think that increasing test coverage is useful anyway, and it's good to commit tests from this patch (the re-formatted version is below).
Also, there is a minor correction for the case of covering index where only part of the columns are keys, others are just INCLUDE columns.
