Problem reproduces only on iOS 17.  
If you try to run iOS application in xcode with address sanitizer you will have an error:

> Address 0x00016bb04080 is a wild pointer inside of access range of size 0x000000000001.  
> SUMMARY: AddressSanitizer: bad-free

Here is code:

```auto
FMOD::Studio::System* _system = nullptr;
FMOD::Studio::System::create(&_system);
_system->initialize(256, FMOD_STUDIO_INIT_NORMAL, FMOD_INIT_NORMAL, nullptr); // Error will be here

```

I’m also experiencing the same issue. ☹

I can reproduce this issue as described, thank you for bringing this to our attention.  
The call stack is inside the iOS libs, possibly a bug in iOS 17. I tried [disabling instrumentation](https://clang.llvm.org/docs/AddressSanitizer.html#disabling-instrumentation-with-attribute-no-sanitize-address) on `Studio::System::initialize`, [suppressing the error](https://clang.llvm.org/docs/AddressSanitizer.html#id10) using `ASAN_OPTIONS`, but find a workaround unfortunately. I have passed this onto the Dev team to investigate further.

We think this might have been an iOS17 bug as we can no longer reproduce this since updating to iOS 17.2.1.  
@maksimomelyanchuk or @seabaa can you please try updating to iOS 17.2.1 or later and confirm whether you still get this ASan crash?

Yes, update solves the problem. Thank you.
