Does COBOL have undefined behavior and lifetime or aliasing issues like C? I have never heard that it does, but don’t know enough to say for sure it doesn’t.

Does COBOL have undefined behavior and lifetime or aliasing issues like C? I have never heard that it does, but don’t know enough to say for sure it doesn’t. Rewriting in C seems like a dodged bullet. Better for it to stay on older safer languages. Most COBOL rewrites I have heard of went to Java, a safe language.
