The recommended way of applying multiple patches is to apply cumulative patches on top of the existing ones [1].

If the first patch introduces some new static/global data, the second patch, being cumulative, will define the same new static/global data. When the second patch is loaded, it will use its own copy of the new data which may not contain the same values as the existing data from patch 1.

Has this problem been considered at all? Are there any known solutions?
