Stack protection will mainly cause a reordering of the stack variables, which causes stack allocation to run in two phases. Also look for other side effects of flag_stack_protect (the variable controlled by -fstack-protect). Other than the documentation at http://gcc.gnu.org/onlinedocs, you could try http://gcc.gnu.org/wiki/GettingStarted for other pointers to internal documentation (I'm not sure if there are pointers to stack-protector docs).
