Follow-up Comment #3, bug #47569 (project grub):

We could also force %pointer (we require the latest flex anyway) which
eliminates this error entirely. This can potentially lead to DoS if someone
gives us too large input file.

Otherwise I'm not sure what logic should be. We start collecting string and
hit "too long" error. What can we do now? Abort parsing of input file
