checklink: error report of Anchors and broken fragments ( again )

I'm using LinkChecker online from http://validator.w3.org/checklink (
with default option values ). The checking result for
http://www.w3.org/TR/REC-html32 show many empty anchors and broken
fragments ( please see the "Result" list below ).

But actually , the reported brokens ( for example "sgml: 53" ) are NOT
a broken at all.
What's the "list of duplicate and empty anchors" mean ? There're no
duplicate or empty anchors at line 68 as listed.

Is there any other options I must offer to get a Right result ? Or is
it a bug in checklink ?

Thanks,
Jesse
