SceneGraph Home/Back button causes reboot on 8.0.1 4047-46

After HLS application has been running for a 10-15 minutes if I press the Home or Back button to exit the application freezes and reboots. I’m doing manual garbage collection and monitoring memory usage, but I can’t see any debugging information because the device reboots without printing to the console.

I am seeing this behavior on Roku Premier 8.0.1 4047-46

I am not seeing this behavior on 3710RW - Roku Express 8.0.0 4128-28

sub showChannelSGScreen()
print"showChannelSGScreen"
m.screen = CreateObject(“roSGScreen”)
m.port = CreateObject(“roMessagePort”)
m.screen.setMessagePort(m.port)
scene = m.screen.CreateScene(“MainScene”)

m.screen.show()

while(true)
msg = wait(5, m.port)
abc=scene.buttonSelected

if abc<>“”
m.screen.close()
end if
msgType = type(msg)
if msgType = “roSGScreenEvent”
if msg.isScreenClosed() then return
end if
end while

end sub
