It's a target bug - the target should ignore the attribute on extern
declarations.
case VAR_DECL:
if (lookup_attribute ("selectany", DECL_ATTRIBUTES (decl)))
{
if (DECL_INITIAL (decl)
/* If an object is initialized with a ctor, the static
initialization and destruction code for it is present in
each unit defining the object. The code that calls the
ctor is protected by a link-once guard variable, so that
the object still has link-once semantics, */
|| TYPE_NEEDS_CONSTRUCTING (TREE_TYPE (decl)))
make_decl_one_only (decl, DECL_ASSEMBLER_NAME (decl));
else
error ("%q+D:'selectany' attribute applies only to "
"initialized objects", decl);
}
thus, restrict processing to !DECL_EXTERNAL
