Subject: [edk2] NvmExpressDxe async application crash with UDK debugger

Hi,

I am testing async io in NvmExpressDxe. The target system is Asrock
Z97 which I have connected to host with serial port where UDK debugger is running. So my application does following

1. CreateEvent
2. Call Passthru
3. CmdSent++;
4. Repeat 1-3 until not ready from driver 5. while (CmdRecd < CmdSent); 4. Close all the events.

CmdRecvd is incremented inside EventCallback. I am allocating both CmdSent and CmdRecvd and passing the address of CmdRecvd in CreateEvent. With this I face WinDbg exception quite often and it says "Target encountered an exception: Vector = 6, Error Code = 00000000".
I can share the application code for more clarity. I am building with /Od and GenFw with --keepexceptiontable

Regards,
Arka
