Sorry. I know here may not be an appropriate place to ask this question. Just don't know where I should go for help. I am debuging a program which is using libc. And in libc it has one code "call *%gs:0x10". Can anybody tell me how to compute the value %gs:0x10 or how I can print this value in gdb?
