To find it on the web dashboard, you first need to go to the specific
bug page (click on one of the bug titles in [1]). E.g.
https://syzkaller.appspot.com/bug?id=4ecce7e55e02002f794e28cbac1682346d423737
At the bottom of such a bug page, there will be a list of crashes. And
in that table, there's a "C repro" column with links to C reproducers
that have been found for the bug.
