Except the fact that your program relies on correct priorities ordering
for starting up tasks, which does not always work if priority coupling is
disabled, your program runs just fine on ARM.

On what platform are you testing this program ? What does 
getconf GNU_LIBPTHREAD_VERSION 
returns on your platform ?
Could you send me the .config of the kernel you are using ?
