[Bug libc/199] New: memory buffer overrun in rare case

["miles at cray dot com" <sourceware-bugzilla at sources dot redhat dot com>]

In __md5_crypt, static variable buflen is set to needed even if realloc fails. 
A later call to this routine will have buflen be too large, and
could cause a write of the end of buf.
 
old version:
      buflen = needed;
 
      new_buffer = (char *) realloc (buffer, buflen);
      if (new_buffer == NULL)
        return NULL;
 
fixed version:

      new_buffer = (char *) realloc (buffer, needed);
      if (new_buffer == NULL)
        return NULL;
 
      buflen = needed;
