meson ought to be smart enough to spot that it's got data from an
incompatible version and just discard its cache rather than
choking on it.
It tries, but it's playing whack-a-mole with Python:
except (pickle.UnpicklingError, EOFError):
raise MesonException(load_fail_msg)
except (ModuleNotFoundError, AttributeError):
raise MesonException(
f"Coredata file {filename!r} references functions or classes that don't
"
"exist. This probably means that it was generated with an old "
"version of meson.")
I'll submit a patch to add TypeError.
