it looks like a problem in the l3 peek code itself  (or its interaction 
with l3doc or hyperref or  ....) ... if one compiles source3.tex

then the index comes out correctly except in one part where it suddenly 
changes to 0:

\indexentry{tl_item:nn=\verb!*&\tl_item:nn&|hdclindex{1248}{usage}}{194}
\indexentry{char_set_active:Npn=\verb!*&\char_set_active:Npn&|hdclindex{1249}{usage}}{194}
\indexentry{char_gset_active:Npn=\verb!*&\char_gset_active:Npn&|hdclindex{1250}{usage}}{194}
\indexentry{char_set_active_eq:NN=\verb!*&\char_set_active_eq:NN&|hdclindex{1251}{usage}}{194}
\indexentry{catcode=\verb!*&\catcode&|hdclindex{1257}{}}{0}
\indexentry{\bgroup =\verb!*&!\{&\iffalse}\fi|hdclindex{1257}{}}{0}
\indexentry{relax=\verb!*&\relax&|hdclindex{1257}{}}{0}
\indexentry{catcode=\verb!*&\catcode&|hdclindex{1258}{}}{0}
\indexentry{\egroup =\iffalse{\fi\verb!*&!\}&|hdclindex{1258}{}}{0}
\indexentry{relax=\verb!*&\relax&|hdclindex{1258}{}}{0}
\indexentry{catcode=\verb!*&\catcode&|hdclindex{1259}{}}{0}
\indexentry{!#=\verb!*&!\!#&|hdclindex{1259}{}}{0}
\indexentry{relax=\verb!*&\relax&|hdclindex{1259}{}}{0}
\indexentry{catcode=\verb!*&\catcode&|hdclindex{1260}{}}{0}
\indexentry{!^=\verb!*&!\!^&|hdclindex{1260}{}}{0}

from that point on it generates 0 and 1 with a few exceptions ...
