I'm not sure this is worth doing; isn't it already a use-after-free? The fact that the memory happens to still be around is just a detail. Possibly the statement should track whether a stream is still open and prevent release instead (converting a use-after-free into a possible leak) |

This came up experimenting in #702. This patch seems to protect from segfaults when reading from a stream when the statement was already closed (
AdbcStatementReleasewas called).Is that something we want to add? (and is it a proper way to achieve it?)
