        PR middle-end/78201
        * varasm.c (default_use_anchors_for_symbol_p): Fix a comment typo.
        Don't test decl != NULL.  Don't look at DECL_SIZE, but DECL_SIZE_UNIT
        instead, return false if it is NULL, or doesn't fit into uhwi, or
        is larger or equal to targetm.max_anchor_offset.

        * g++.dg/opt/pr78201.C: New test.
