What did you do?

Compiling our internal codebase with go 1.17 aborts with a panic. Based on the stack trace the problem seems to originate in escape analysis.

I can't share the full source, but this is the bit that escape analysis was working on as it crashed:

	e.stdout.Logf("unloaded dispatcher from %s\n", e.netns)  # loading.go:44
	return nil
}

func upgrade(e *env, args ...string) error {
	set := e.newFlagSet("upgrade")
	set.Description = "Upgrade the tubular dispatcher, while preserving present state."
	if err := set.Parse(args); err != nil {
		return err
	}

env is simply a type struct containing some string, interfaces and function pointers.

Would you mind making a minimal reproducer? It's hard to investigate further without more information about the code.
