【求助】gdb调试的问题

用gdb调试程序如下5`^r;|'YG-]v
#include <stdio.h>ME'Tv&X;@
void my_print (char *string)
{
printf ("The string is %s\n", string);
}
void my_print2 (char *string)
{
char *string2;q,y%MP+L_
int size, i;
size = strlen (string);
string2 = (char *) malloc (size + 1);
for (i = 0; i < size; i++)q'`"W B`wG!t
string2[size - i] = string[i];
string2[size+1] = '\0';
printf ("The string printed backward is %s\n", string2);
})aU0l0B5?/s
main () e?HWU^I^w
{M"W*V;_ {8l
char my_string[] = "hello there";
my_print (my_string);
my_print2 (my_string);
}
在string2[size - i] = string[i];这行用break设断点
用watch观察变量string2［size－i］:oP\k6i
再输入next后按回车，却显示
(gdb) next$t2l[L;f\
warning: Could not remove hardware watchpoint 2.
Warning:
Could not insert hardware watchpoint 2.VVt!|+Z1j!Q
Could not insert hardware breakpoints:6D.WW `1@6z
You may have requested too many hardware breakpoints/watchpoints.C/{l5omB
请问各位，哪里出错了

操作问题？没见过这种错，重新调试呢？

我这样改了，输出是：
The string is hello there
The string printed backward is
