Iterator invalidation can lead to memory unsafety in C++, usually due to a pointer or reference becoming dangling, but most other languages just treat it as a correctness problem: GC avoids the problem of invalidating pointers. As my parent comment hinted, some languages, like Java, try to detect (some occurrences of) these problems at runtime.
