4 // "g_points" array where the following things are wrong:
5 // - the DW_TAG_array_type won't have a subrange info
6 // - the DW_TAG_variable for "g_points" won't have a valid byte size, so even
7 // though we know the size of PointType, we can't infer the actual size
8 // of the array by dividing the size of the variable by the number of
9 // elements.
