I tried it several times, on several machines and with several lynx
versions.  So far I could not get Lynx to crash in the manner described.
However I can get it to dump core when quitting Lynx shortly *after*

None of that is very surprising (and it is arguably not a lynx bug),
given the nonsensical HTTP headers that are being sent.

There is something else "unusual" about followin that link: it is a
POST form submission, but there aren't any form data.  Lynx sends a
POST request with "Content-Length: 0" (not illegal, but unusual AFAIK.
I don't think there is any good reason for using a form in this case
at all, a simple link should do just as well.  I have the suspicion
that all this is done just to get a specific optical "button" effect
in some GUI browser.)

But if they fix it now we may miss the chance to catch the bug..
