| // I made this example after noting that I was unable to display an unsized |
| // static class array. It turns out that gcc 4.2 will emit DWARF that correctly |
| // describes the PointType, but it will incorrectly emit debug info for the |
| // "g_points" array where the following things are wrong: |
| // - the DW_TAG_array_type won't have a subrange info |
| // - the DW_TAG_variable for "g_points" won't have a valid byte size, so even |
| // though we know the size of PointType, we can't infer the actual size |
| // of the array by dividing the size of the variable by the number of |
| // elements. |
