Haha! Good luck with that! If the same part (source program) is involved, you really have only one practical choice: code your fix on top of the program known to be in error and hope they resolve their issues soon.

Coding your fix on top of an earlier, working version of the program would require its PTF to have an NPRE() to ensure the SPE PTF is restored before the new fix can be applied. In this case, the eventual fix for the broken SPE will need to supersede both PTFs.

I haven't seen this done in the last couple of decades at least, but it is technically possible.
