[Bug c++/19916] New: Segmentation fault in __static_initialization_and_destruction_0

[jgrimm2 at us dot ibm dot com]

The following testcase segfaults on 3.4.4 and 3.4.0, but runs to completion on
3.2.3.

Note this test won't even compile on mainline, so I don't know if the same
problem exists there.   See:
  http://gcc.gnu.org/bugzilla/show_bug.cgi?id=19878

I think this was caused by:
2003-07-22  Mark Mitchell  <mark@codesourcery.com>

        Eliminate use of POINTER_TYPE for pointers-to-members.

Now that 19878 has been fixed, we can see that this does in fact fail on the
mainline as well.
