What did you do?
./v -g -o vdbg cmd/v && ./vdbg src/main.v

module main

fn main() {
	x := 42
	println(if x == 69 {"A"} else {"B"})
}

What did you expect to see?

When the program is compiled normally, B gets printed, as expected. When compiled with -autofree, a C error appears.

What did you see instead?

B
