I changed the cross compiler from version "arm-linux-gnueabihf-gcc (Ubuntu/Linaro 5.4.0-6ubuntu1~16.04.9) 5.4.0 20160609" to "arm-linux-gnueabihf-gcc (Linaro GCC 7.2-2017.11) 7.2.1 20171011". The problem solved but I don't know why! -- You received this message because you are subscribed to the Google Groups "Jailhouse" group.
