I honestly can't imagine how I introduced a bug in this area with the 
pointer-tagging patch!

Can you generate AutoApply.raw_s before and after the pointer-tagging 
patch, and send me the files please?  Use -keep-raw-s-file, and presumably 
you need to recompile stage1 after applying the patch, but not the libraries.

Cheers,
