I just compiled wget 1.7 under HP-UX and discovered that it dumps core
on -every- invocation, whether with no args, a single arg of --help or
--version, or a URL. 1.6 appears to do the same thing. 1.5.3 (the
version I've been using up until now), and every previous version of
wget I've ever used, doesn't do this. I have not changed anything
about my compiler or anything else since building 1.5.3.
Some simple debugging with gdb led me to discover that my copy of
/usr/local/etc/wgetrc is actually a directory, which contained a file
called sample.wgetrc. I have no idea if this was the way things used
to work under earlier wget releases, or if I was just trying to put
the sample file somewhere I'd remember it later when I first set this
up years ago, but versions of wget before 1.6 were at least
well-behaved enough to ignore this. (I don't use a global init
anyway.) 1.6 and 1.7, on the other hand, explode and dump core
without giving the user a clue what might be wrong. The code that
parses this init file (and the other places where they might hang out)
should (a) warn if the file isn't an ordinary file or a link, but is
instead anything else (a directory, something weirder...), and (b)
should not blow up if the file's contents are peculiar (e.g., binary).
System information, in case it has any relevance:
% uname -a
HP-UX oob B.10.20 A 9000/725 unknown
The failure (in 1.7; 1.6 is similar except for line number):
% wget --version
utils.c:906: failed assertion `length > 0'
