Bug with recovery actions Reboot Message and Run A Program Command

[WantStuff]

Both the Reboot Message and run a program Command properties get corrupted (show random characters).
This appears to be due to incorrect memory/pointer allocation of ServiceFailureActionsInfo ( SERVICE_FAILURE_ACTIONS and SC_ACTION[] ).

FYI: I've created my own recovery actions code and have found it works if I use the below code to allocate memory and return a pointer the SC_ACTION list.
Hopefully this will help you identify the issue.

private static SafeMemoryHandle StructureArrayToPtr<SC_ACTION>(IList<SC_ACTION> structureArray)
{
    if (structureArray == null || !structureArray.Any())
        return new SafeMemoryHandle();
    
    var elementSize = Marshal.SizeOf(typeof(SC_ACTION));
    var arrayLength = structureArray.Count;
    
    // Allocate enough unmanaged memory to hold the struct array and collect a pointer to it. 
    var totalArraySize = elementSize * arrayLength;
    var pointerToStruct = new SafeMemoryHandle(Marshal.AllocHGlobal(totalArraySize));
    
    // Populate the allocated memory with each structure.
    for (var i = 0; i < arrayLength; i++)
    {
        var offset = elementSize * i;
        var elementPointer = IntPtr.Add(pointerToStruct, offset);
        Marshal.StructureToPtr(structureArray[i], elementPointer, false);
    }
    
    return pointerToStruct;
}
