[Bug general/5512] New: list command NPEs when trying to list a multi-threaded task

["rmoseley at redhat dot com" <sourceware-bugzilla@sourceware.org>]

After running a process that is multi-threaded and it stops at a break point,
trying to do a "list" causes an NPE.

(fhpd) run ../pkglibdir/funit-threads-looper
Attached to process PID
(fhpd) break bak
(fhpd) go

  100        {
  101          //fprintf (stderr,"attach %s pid=%d -task tid=%d -cli\n", myname,
getpid(), gettid());
  102          int a = 0;
  103          int b = 0;
  104          int c = 0;
  105          while (1)
  106            {
  107              a++;
* 108              b++;
  109              c++;
  110              if (a + b > 4)
  111                {
  112                  a = a - c;
  113                  b = b - c;
  114                  c = 0;
  115                }
  116            }
