Assembly instructions ( following the standard x 8 6 - 6 4 calling conventions ) : g: leaq - 8 ( % rdi ) ,
Assembly instructions following the standard x calling conventions: g: leaq rdirsi leaq rdi,rdi,rdi call f ret Corresponding C code skeleton: long glong z return f; There is a specific argument to g that causes a Segmentation Fault. You should be able to find the number from looking at the assembly code, but you can also confirm by putting the assembly code for g and f in a s file along with the code below. Then change the argument that main calls g with, assemble to an executable with gcc and run the program. main: movq $rdi call g movq $rax ret LC: text globl main type main, @function Question SUBMITTED Argument Which numeric argument to g causes a segfault?
