在gdb中交互分解

GDB不能直接这样做,但你可以非常接近:

cat > t.c <<EOF
char buf[512];
int main() { return 0; }
EOF

gcc -g t.c -o t

gdb -q ./t
Reading symbols from /tmp/t...done.
(gdb) b main
Breakpoint 1 at 0x8048352: file t.c, line 2.
(gdb) r

Breakpoint 1, main () at t.c:2
2   int main() { return 0; }
(gdb) set buf[0] = 0x58
(gdb) set buf[1] = 0xef
(gdb) set buf[2] = 0x22
(gdb) x/i buf
   0x8049560 <buf>: pop    %eax
(gdb) q
