[Lynx-dev] Segmentation fault when lynx - get several lines of input with the first one not being a correct URL

[Pascal Terjan]

For exemple :

$ echo "a
free.fr" | LC_ALL=C lynx -
Looking up  'a' first
Looking up  'www.a.com', guessing...
Erreur de segmentation

If the first one is correct, it is OK as lynx will draw its interface
before looking at the other one.

I found this by trying to feed some HTML on stdin :)

Program received signal SIGSEGV, Segmentation fault.
