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.

We want to make sure clang and llvm-gcc handle this correctly.
