Description Jaak Ristioja 2008-01-11 19:20:46 UTC

The following wget command crashes:
  wget -r --delete-after http://localhost/haha.php

If the web server redirects /haha.php to itself (tested using HTTP 302), wget segfaults after the redirection following limit is exceeded. Resulting wget output (beginning omitted) and gdb backtrace.

--21:07:09--  http://localhost/haha.php
           => `localhost/haha.php'
Reusing existing connection to localhost:80.

please retest with wget-1.11 and if it still fails, re-open with the new output

Comment 2 Jaak Ristioja 2008-01-28 18:43:27 UTC

Fixed in wget-1.11. Thanks.
