Actually normal python installations do not cause problem, only debugging versions do.

Anyway, if you think that this doesn't count as an argument, there is
nothing that we can do from PG-side except drop returning SETOF as
iterator/generator and only allow return SETOF as list.

Can't we detect a debug build and disable the feature?

Yes, we can, but newer python versions are already fixed.

So, what about this in configure:
if --with-python && test_iterator_app_crashes
  # errcode(FEATURE_NOT_SUPPORTED), errmsg(patch your python)

In this way we disable feature only if it is absolutely neccessary and will give developer enough information how to fix it.
