    I created a small (relatively) test project that demonstrates the issue. Submitted as bug (Case 825650).

    Project reproduces 100% a crash calling the finalizer of RNGCryptoServiceProvider when using IL2CPP as the scripting engine.

    There are several calls to post https requests to a server. This works fine with one request but, crashes when there are several. Each request spawns a thread which makes the call and waits for a response from the server.

    When there are multiple requests active at once it seems as though a pointer to a RNGCryptoServiceProvider is freed twice, causing the abort.

    Works as expected under the mono scripting engine.
