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.
