What steps will reproduce the problem?
1. run `tail -f somefile`
2. use gcore to core dump 
3. run `cortex -i tail-vanilla.core -f all`

What is the expected output? What do you see instead?

$ cortex -i tail-vanilla.core -f all

When I compile cortex I get several warnings. All very similar to each other 
regarding format strings I guess:

‘unsigned int’, but argument 3 has type ‘Elf64_Addr’ [-Wformat=]
