Started to fail with r268252:
PR c++/89001 - mangling of reference temporaries
It used to be the case that the mangled name of a reference temporary
didn't
need to be standardized, because all access would be through the reference.
But now constant expressions can look through references and so different
translation units need to agree on the address of a temporary in the
initializer of a reference with vague linkage.
* cp-tree.h (struct saved_scope): Add ref_temp_count.
(current_ref_temp_count): New macro.
* mangle.c (mangle_ref_init_variable): Use it.
* typeck2.c (store_init_value): Clear it.
* call.c (make_temporary_var_for_ref_to_temp): Copy public and
comdat.
