Any chance that you have a look at the swig issue (#1114586), since
you are listed as uploader of the package?
The issue in Bug#1114586 can indeed be fixed by either upgrading the
swig package to the new upstream version 4.3.1 or by applying the
patch that you indicated [*]. However, the plplot package would still
FTBFS on unstable, because the gnat stack is not yet updated to gcc 15
(see Bug#1097622).
I think we could ignore the plplot package for the Octave 10 transition.
