I don't know why PAX always kill my process. The platform is powerpc and OS is Linux. From the kernel log, I can see as following:
PAX: From 147.128.23.67: execution attempt in: , 100a3000-10175000 100a3000 PAX: terminating task: /mnt/ecim/pau6000agent/bin/agent_z(agent_z):1744, uid/euid: 0/0, PC: 100a318c, SP: bbc85aa0 PAX: bytes at PC: 396001fc 4bfffbdc 39600200 4bfffbd4 39600204 gpr_get: partial register set
Google told me to try with 'paxctl -m ./agent_z' or 'paxctl -z ./agent_z', but none of them helps. Actually, 'agent_z' doesn't have any PAX flags. So it really confuse me why PAX always kill 'agent_z'
file ./agent_z does not have a PT_PAX_FLAGS program header, try
conversion root@QorIQ:/mnt/ecim/pau6000agent/bin> paxctl -v ./agent_z PaX control v0.5 Copyright 2004,2005,2006,2007 PaX Team file ./agent_z does not have a PT_PAX_FLAGS program header, try conversion
Here is the information of the gcc I am using. And moreover, as suggested by others, I also have tried adding -O1/-O2/-O3 flags when compile, but none of them works.
