Bug#535106: libc6-i386: getaddrinfo() fails

[Pieter-Tjerk de Boer <ptdeboer@cs.utwente.nl>]

Package: libc6-i386
Version: 2.7-18
Severity: normal

The function getaddrinfo() in the i386 compatibility library returns
-2 (i.e. EAI_NONAME) for any query, while getaddrinfo() in the amd64
library does find the host and returns 0.

Here's a trivial test program, called test.c, which prints the
getaddrinfo() return value for a query for www.google.nl :

  #include <sys/types.h>
  #include <sys/socket.h>
  #include <netdb.h>
  #include <stdio.h>
  int main(void)
  {
     int e;
     struct addrinfo *a;
     e=getaddrinfo("www.google.nl","80",NULL,&a);
     printf("%i\n",e);
     return 0;
  }

And this is the result, compiling first as native amd64 code, and
then as i386 code:

  $ cc test.c -o test
  $ ./test
  0
  $ cc test.c -o test -m32
  $ ./test
  -2
  $ ldd ./test
          linux-gate.so.1 =>  (0xf7f9e000)
          libc.so.6 => /lib32/libc.so.6 (0xf7e35000)
          /lib/ld-linux.so.2 (0xf7f9f000)
  $

Obviously, I would expect both invocations of ./test to print 0.
