The error tells you - the initialiser is not constant.
Sure, it's constant in the first line, but 'testy' is a variable, so you are
trying to use a variable as a constant initializer in the second line. That
isn't allowed.
If you think about how constant initializers in C actually work, at the machine
code/assembler level, it should be clear why it isn't allowed.
