…immutable objects (pythonGH-148698) Forbid marshalling recursive code, slice and frozendict objects which cannot be correctly unmarshalled. Reject invalid marshal data produced by marshalling recursive frozendict objects which was previously incorrectly unmarshalled. Add multiple tests for recursive data structures. (cherry picked from commit 2e37d83) Co-authored-by: Serhiy Storchaka <storchaka@gmail.com>
