Hi Stefan,

Thanks for the patch! With the patch applied, then "see" no longer 
crashes on those particular routines. Interestingly enough, digging 
further into the BIOS I still see some discrepancies between the source 
code and the detokenized version:

0 > see find-device
: find-device
     2dup " .." strcmp 0= if
     2drop active-package dup if
       >dn.parent @ dup 0= if
         (lit) throw active-package! exit 0 -rot path-resolution 0= if
           false exit active-package swap true path-res-cleanup 

In this case, (lit) should be "..". And also:

0 > see (find-dev)
: (find-dev)
             active-package -rot (lit) catch if
             3drop false exit active-package swap active-package! true

And here (lit) should be "[']". Am I right in thinking that it should be 
possible to reconstruct any source exactly (minus formatting) from a 
tokenized input?

Many thanks,
