Global and static variables locate at data segment b. When a function is called, memory is allocated on the stack to hold parameter values, local variables, and the address of the calling function c. the struct is aligned based on the greatest alignment requirement of it's members. according to elf or ABI? do the segment originate from coff? xvzhaobin
