> If bar() returns a char[], it means it returns a dynamic array. char[8] inside
bar() is allocated on the stack, so if you convert a static array to a dynamic
array, it doesn't get copied (no return by value), the dynamic array is just a
reference to the stack memory, and this is a bug. If bar returns a char[8] there
is no error in D2 because fixed-sized arrays get copied by value.
