Most likely this means that you are looking at unlinked (i.e. unrelocated) code. Did you run objdump on a .o file? In this case, the actual call address is in the relocation. Try objdump -r and you will see a relocation for the address 0x4000000000000722 that contains the actual call target. Also try objdump -r -d. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
