// 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.
