Re: [Bug-wget] segment fault while downloading .tar.gz file

2018-02-23 Thread Tim Rühsen 
Hi Jay,

it seems related to https://gitlab.com/gnuwget/wget2/merge_requests/353.

Maybe you like to drop in there...

In short: the server ignores 'Accept-Encoding: identity' and gives us a
'Content-Type: gzip'.

If you build wget2 with libz (just install zlib1-dev and ./configure
again), the problem shouldn't occur and you can go on fixing issue 315.


With Best Regards, Tim

[Bug-wget] segment fault while downloading .tar.gz file

2018-02-23 Thread Jay Bhavsar 
So, I was trying to resolve this
 issue.

Command I run:

./wget2_noinstall http://www.lysator.liu.se/~nisse/archive/nettle-3.4.tar.gz

What I get:

[0] Downloading 'http://www.lysator.liu.se/~nisse/archive/nettle-3.4.tar.gz'
...
Saving 'nettle-3.4.tar.gz.8'
Segmentation fault (core dumped)

Investigating with gdb:

I haven't been able to reproduce this issue with any other url. Also, wget2
freezes with all https urls. Anyone seen something like this before? Is
this real issue or my system acting up? In any case, should I dig further
and create issue?
