I don't know what that means. I don't see how auto-generated code would fix my problem. The regex parser should return an error to the caller if the regex exceeds some limit.

Dynamically growing the stack sounds like a cute hack. I doubt I'd consider it superior to just using the heap though.

You can use that to make stack overflow a (relatively) graceful error instead of a segfault.
