        * dwarf2out.c (dw_loc_list): If crtl->has_bb_partition, temporarily
        set in_cold_section_p to the partition containing loc_list->first.
        When seeing loc_list->last_before_switch node, update secname and
        perform range_across_switch second partition handling only after that.

        * gcc.dg/debug/dwarf2/pr82718-1.c: New test.
        * gcc.dg/debug/dwarf2/pr82718-2.c: New test.
