            Bug ID: 27520
           Summary: gaiconf_init() segfaults on wrong entry in gai.conf
           Product: glibc
           Version: 2.32
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: network
          Assignee: unassigned at sourceware dot org
          Reporter: speedprogde at googlemail dot com
  Target Milestone: ---

Created attachment 13288
  --> https://sourceware.org/bugzilla/attachment.cgi?id=13288&action=edit
backtrace from running curl http://www.google.de

So i added a label to gai.conf file and forgot to add the mask like this:
label fd81:b62:bcf6::20 1
which of cause is worng, but after doing it every program that seem to try and
use ipv6 segfaulted in libc.
Sadly I don't have the vanilla glibc but instead one with the gentoo patches.
So the backtrace from gdb that I attached has some wrong line numbers.
I checked the gentoo patches and they do not touch the gaiconf_init() function.
And line 1867 should be 1872 in the original 2.32 source.
