CreateOverlay causes EXCEPTION_ACCESS_VIOLATION

[listvin]

Hello, Giuseppe

Quite a long time I have been struggling with mentioned error.
I'm running Windows 10 x64, HTC Vive, nvidia 1070 and amd fx-8320.

Following code:

import openvr.lib.*
import java.nio.LongBuffer

fun main() {
    println("java ${System.getProperty("java.version")} ${System.getProperty("sun.arch.data.model")}bit")
    println(vr.isHmdPresent)
    println(vr.isRuntimeInstalled)
    println(vr.runtimePath)

    val ivr = vr.init(VRApplication.Overlay)
    println("ivr error code: $ivr")

    println("vrOverlay.isInterfaceVersionValid = ${vrOverlay.isInterfaceVersionValid}")

    val testOverlayHandle = VROverlayHandleBuffer.allocate(1).also {
        println(it.limit())
        vrOverlay.createOverlay("test:overlay", "test overlay", it) // <- access violation
//        vrOverlay.createDashboardOverlay("test:overlay", "test dashboard overlay", it, LongBuffer.allocate(1)) // <- no exception produced here
    }.get(0)

    vrOverlay.setOverlayFromFile(testOverlayHandle, "duck.png")
    vrOverlay showOverlay testOverlayHandle

    Thread.sleep(2000)

    vrOverlay hideOverlay testOverlayHandle
    vrOverlay destroyOverlay testOverlayHandle

    vr.shutdown()
}

Produces output:

C:\Program Files (x86)\Steam\steamapps\common\SteamVR

vrOverlay.isInterfaceVersionValid = true

Have tried also under Java 11 x64 both 1.2.10 release and cbc252e with about the same result (but pc like 0x7ffc########).
Seems magical to me that createDashboardOverlay doesn't cause any errors.

Attaching Visual Studio to native code shown access violation with pc=0x00000000, can it be a null pointer?
PDB file for vrclient.dll isn't available hence I don't see any further options for native debug.
hs_err_pid15344.mdmp and hs_err_pid15344.log

SteamVR is 1.6.10, though I expect it to be backward-compatible, declarations of CreateOverlay are similar in openvr.h of 1.2.10 and of 1.6.10. I'd like to try older versions of SteamVR, but I don't see an obvious way of safe downgrade.

P.S. helloVr_OpenGL works as a charm with my setup and SteamVR 1.6.10.

Hi Fedor,

let me update a couple of things (lwjgl and kotlin the most important) and then I'll try to replicate the crash

I'll let you know
