Re: running "latest" version of wget2 gives a core file.

[Tim Rühsen]

Hi,

I can't reproduce here. Using your command line gives the expected

Failed to resolve wget (Name or service not known)
Failed to connect: General error
...

Since 'wget' is not resolvable, the code path shown by gdb should not
have been traversed.

To track this down I need your help.
- have a look if any old libwget and/or wget2 are lying around (remove
old ones)

- try to reduce the options, e.g. leave away -A ... and so on., to find
out which options don't combine.

- add '--d -oout.txt', send us out.txt and your config.log. if there is
private information included, remove it and/or send the files to me
directly.

Regards, Tim
