Unrelated to any ABI or API problems, a use-case of mixing different
versions  of the libraries strongly advised against ever using or a
distribution enabling such use, because its hardly ever tested, and
results may be rather unpredictable, especially with a lot of
applications sadly still using some of the API "incorrectly".
