Description Dan Egli 2004-08-28 05:11:37 UTC
Description of problem:
when using Samba dns module to resolve dns names via smb, elinks will
not locate any domain, and always dumps to screen. I cannot copy/paste
but an approximation is:

ap, Mimetypes files), Bookmarks, Cookies, Forms History, Global
History, URI rewrite


elinks[dump_backtrace+0x1d][0x80c748d]
elinks[0x8090674]
elinks[0x80909af]
/lib/tls/libc.so.6[0x791f38]
/lib/libnss_wins.so.2[0x3c31b0]
/lib/libnss_wins.so.2[init_                    4e]
/lib/libnss_wins.so.2[init_                   


and so on. I would prefer to not type the whole thing.


Version-Release number of selected component (if applicable):
elinks-0.9.1-1

How reproducible:
Always. Gaurenteed

Steps to Reproduce:
1. modify the hosts line of /etc/nsswitch.conf to have wins BEFORE dns
2. run Elinks
3. Watch the crash
  
Actual results:

Screen as shown above.

Expected results:

Should work.

This is already know "bug":
   http://bugzilla.elinks.or.cz/show_bug.cgi?id=453

elinks and samba define same function name "convert_string()", but
each does something other... and if elinks calls getaddrinfo() it
loads libnss_wins.so with this function into elinks and it crash.

Solutions: never use and export common names in samba, elinks and all
others projects!
