No, the problem is much more basic than "taking over your computer," it looks like the compiler generates incorrect assembly. Upon visual inspection I found a huge class of infinite loops, but I am sure there are subtle bugs that can corrupt running user/OS processes... including Docker, potentially. Containerization does not protect you from sloppy native code.

This is an understatement. A more useful warning would be "don't use it to compile any code with a while loop." Seriously, this compiler looks terrible. Worse than useless.

If you really want AI to make a toy compiler just to help you learn, use Python or Javascript as a compilation target, so that the LLM's dumb bugs are mostly contained, and much easier to understand. Learn assembly programming separately.

You have not provided any evidence that can be refuted, only vague assertions.

The compiler is indeed useless for any purpose other than learning how compilers work. It has all the key pieces such as a lexer, abstract syntax tree, parser, code generator, and it is easy to understand.

If the general approach taken by the compiler is wrong then I would agree it is useless even for learning. But you are not making that claim, only claiming to have found some bugs.
