state *is* set to null, before your constructor is called. The
access is not "before it was set".
Could the compiler *possibly* flag this as an error? It could,
but it doesn't, and likely won't in the future.

I'm confused. If state is set to null on struct initialization,
then why does accessing that memory segfault? Shouldn't the if
condition just fail?
