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