Running

def test() -> i32:
    temp: i32 = 0
    return temp

x : i32 = test()
# print(x)  Will give segmentation fault

gives code generation error: Function code not generated for 'test' .

But declaring and assigning in different line

x : i32
x = test()
print(x)

compiles successfully.
Not sure if this is intentional. This type of code runs fine in CPython.
