App crashes when Crashlytics catches an exception

Question

I've integrated Crashlytics into my Xamarin.iOS project, Crashlytics starts, application appeared at crashlytics site. But then, when crashlytics catches exception, it crashes with the next error:

signal %d, info %p, uapVoid %p

Unable to setup stack %s

I'm starting crashlytics and AppDomain.CurrentDomain.UnhandledException like this (method description):

public override bool FinishedLaunching (UIApplication app, NSDictionary options)
{
    IntPtr sigbus = Marshal.AllocHGlobal (512);
    IntPtr sigsegv = Marshal.AllocHGlobal (512);

    // Store Mono SIGSEGV and SIGBUS handlers
    sigaction (Signal.SIGBUS, IntPtr.Zero, sigbus);
    sigaction (Signal.SIGSEGV, IntPtr.Zero, sigsegv);

    ...

    Crashlytics.Crashlytics.StartWithAPIKey("myApiKeyHere");
    AppDomain.CurrentDomain.UnhandledException += (object sender, UnhandledExceptionEventArgs e) => {
        ...
    };

    sigaction (Signal.SIGBUS, sigbus, IntPtr.Zero);
    sigaction (Signal.SIGSEGV, sigsegv, IntPtr.Zero);

    Marshal.FreeHGlobal (sigbus);
    Marshal.FreeHGlobal (sigsegv);

    return true;
}
