updated for version 7.3.055 Problem: Recursively nested lists and dictionaries cause a near-endless loop when comparing them with a copy. (ZyX) Solution: Limit recursiveness in a way that non-recursive structures can still be nested very deep. Files: src/eval.c, src/testdir/test55.in, src/testdir/test55.ok
