Created attachment 7837

Same example source as 11695, demonstrating different DWARF bug

The output of 
clang++ -g -O0 const.cpp
(source attached)
followed by dwarfdump -i a.out
shows in part:

< 2><0x000000e9>      DW_TAG_class_type
          DW_AT_sibling               <0x000007b7>
          DW_AT_containing_type       <0x000000e9>
          DW_AT_name                  "ios_base"

but the DWARF4 spec says DW_AT_containing type should
only appear on DW_TAG_ptr_to_member_type.

Using clang HEAD on Ubuntu 11.10 x86.
