The problem is that if we see in BLOCK_NONLOCALIZED_VARS current_function_decl, we don't treat it as declaration (which is everything that is not current_function_decl among other things), therefore we endlessly recurse on it. If we are already processing the current_function_decl, we have a DIE created for it and supposedly also at the correct position in the DIE tree, and that is all we care for declarations, we don't do further processing for those.
