I'm asking about parameters because if I recall correctly the arguments were stored on program stack, so I thought of maybe some stack alignment issue or something similar. Maybe you can modify lvgldemo_main and place print some message to console + sleep(1); in a loop just after it is entered? Not sure if that will give us much, but worth of trying to get some information.
