[patch] Fix PR c++/27805

[Lee Millward]

The value of ptrmem_type is not what causes the ICE in this particular
testcase. Upon entry to build_m_component_ref datum has
error_mark_node as it's tree type which causes the failure on the
following line:

objtype = TYPE_MAIN_VARIANT (TREE_TYPE (datum));

Cheers,
Lee.
