[Bug libc/6843] New: getaddrinfo_a segfaults

[aurelien at aurel32 dot net]

The following code segfaults with at least glibc >= 2.7 (and CVS). It works 
correctly with versions 2.3.X. I have tested versions in between.

#define _GNU_SOURCE

#include <string.h>
#include <netdb.h>
#include <signal.h>
#include <stdio.h>

int
main (void)
{
#define N 10
  struct gaicb reqmem[N];
  struct gaicb *req[N];
  int n;

  for (n = 0; n < N; ++n)
    {
      asprintf (&reqmem[n].ar_name, "test%d.test.redhat.com", 140 + n);
      reqmem[n].ar_service = NULL;
      reqmem[n].ar_request = NULL;
      reqmem[n].ar_result = NULL;
      req[n] = &reqmem[n];
    }

  getaddrinfo_a (GAI_NOWAIT, req, N, NULL);
  
  return 0;
}
