Hi,

Sorry if this is a known issue, I could find it from a quick search 
through the archives.

I accidentally created a redirect from a page to itself - page A
redirected to page B redirected to page B etc. The checklink script
read the redirections fine, but when it came to printing out
the report it hung. I had to run the script under the perl debugger to 
discover what was going on.

The problem is in &get_redirects - it seems to declare a %seen hash which
would be the obvious thing to use to check for loops, but it doesn't use
it. I'd be happy to supply a patch if anyone wants.

Cheers,

Ganesh
