New description:
While attempting to debug error messages relating to invalid
DW_AT_specification attributes with programs generated by our newer gcc4,
I'm running into issues digging into what's actually going on because
Debugger isn't properly able to represent the AttributeValue class.
The anonymous union is simply shown as a blank value node that expands to
another instance of the AttributeValue class with the same blank value
node ad infinitum. At the moment I'm not really clear as to what's going
on though, since the same union declared outside of a class works fine.
Attached a simplified test program which reproduces the issue ; the
compiler used to generate the DWARF output in question doesn't appear to
matter, it's reproducible with both 2 and 4.
