Trick was to use the stack-protector-guard option otherwise gcc expect the canary value to be stored on the Thread Local Storage of the current thread. That does not work the same way for us, so trying to access TLS at %gs (the canonical place for the TLS), where gcc expect the canary to be storeg, lead to system reboot as it is not setup.
