It is immaterial if it is legal or nor, because it is impossible.
The order of initialisation of a class's base-classes and members is not
dependent on the order they are specified in in the initializer-list, but
rather the order they are declared in in the class's definition.

If you compile your example with g++, with the warning flags -Wreorder or
-Wall, then g++ will complain that the initialization order is different
from the order in your initializer list.
