The code is very easy:

#include <stdio.h>

main()
{
char *str;
int size = 10;
int i;
str = (char*)malloc(size);
for (i = size; i > 1; i--)
str[size - i] = '*';
str[size - 1] = '\0';
printf("str=%s\n", str);
}

I want watch "str[size - i]" in gdb, but it report error:
gcc -g -o test test.c

gdb testgdb test

(gdb) b 10
Breakpoint 1 at 0x80483e0: file test.c, line 10.

(gdb) r
Starting program: /root/tmp/test
Breakpoint 1, main() at test.c:10
10 str[size - i] = '*';

(gdb) watch str[size - i]
Hardware watchpoint 2: str[size - i]

(gdb) n
warning: Could not remove hardware watchpoint 2.
Warning:
Could not insert hardware watchpoint 2.
Could not insert hardware breakpoints:
You may have requested too may hardware breakpoints/watchpoints.

it only report error on Fedora Core 3.
i tseted it on redhat linux 9.0/Fedora Core 1, no error.
