The initial // backing array for the slice was allocated in the .data section, // which is fine, but the backing array was not registered as a GC // root. package main import ( "runtime" ) type s struct { str string } var a = []struct { str string }{ {""}, } var b = "b" var c = "c" func init() { a[0].str = b + c } func main() { runtime.GC() if a[0].str != b + c { panic(a[0].str) } }
