To illustrate unreliable approach, please compile following test:
--cut here--
extern void foo (void *);
int test(void)
{
__label__ bla;
foo (&&bla);
bla:
return 0;
}
--cut here--
gcc -O2:
test:
.L2:
pushl %ebp
movl %esp, %ebp
subl $8, %esp
movl $.L2, (%esp)
call foo
xorl %eax, %eax
leave
ret
The passed argument doesn't represent return address.
