What I described is an optional compiler optimization. The compiler is free to avoid the GC allocation for an array literal initializer if it is possible to do so. If you were to, e.g., return the array from the function, it would 100% for sure be allocated on the GC and not the stack. In practice, I don't know if any of the compilers actually do this.
Anyway, if you care when memory is deallocated, then the GC isn't the right tool for the job. The point of the GC is that you don't have to care.
