Hi,
the reason is that type "struct C264" has DECL_ASSEMBLER_NAME (TYPE_NAME
(type))
set to  <identifier_node 0x7ffff660f3c0 10ltotests_04C284>
which makes LTO to consider this type to be C++ type conforming ODR
rule.

I am not really fluent with d.  Does d have something like ODR?
If it doesn't then we need to arrange free_lang data to not consider d
types to be C++ ODR types.

The type seems to not be seen by free lang data which by itself is
confusing.
