Jonathan Wakely <redi at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |NEW --- Comment #4 from Jonathan Wakely <redi at gcc dot gnu.org> --- Since this seems to be confusing people, the bug is not "the URL gives a 4040 error", it's that there is no index-INIT_005fEXPR-1907 anchor that the #index-INIT_005fEXPR-1907 fragment can link to. So the index entry links to the top of the page, not to the docs for INIT_EXPR. And that is not fixed, because there are no ID or NAME attributes anywhere in the page, so no #foobar fragment will ever link anywhere except the top of the page.
