I haven't been able to reproduce on Ubuntu either. Trying to think if there's any other distribution/kernel where this option is likely to work differently.
The reproduction steps point to another potential problem -- the regular and guru mode scripts are being compiled differently, but they appear to be treated equivalently by stap's compilation cache. Therefore deleting the cache changes the outcome of $ stap helloworld.stp -g
