Hi, I'll try to dig up an older build environment and see what happens. Still if it is a compiler bug, I wonder what makes RCU/kernel code trigger this and not other code? I also notices that the interface-renaming rcu problem which occurs in a different part of the RCU code, when "fixing" according to the patch supplied previously in this thread, the code I hit the bug again if I revert from using CFLAGS=-02 to just using CFLAGS=-0. So kernel optimization flags can trigger this bug it seems. /Magnus
