Those should be 999.
If the program still crashes, check the stack-limit:
$ ulimit -a
core file size (blocks) unlimited
data seg size (kbytes) unlimited
file size (blocks) unlimited
max memory size (kbytes) unlimited
stack size (kbytes) 2048
cpu time (seconds) unlimited
max user processes 256
pipe size (512 bytes) 8
open files 1024
virtual memory (kbytes) 2099199
$ ./test
Segmentation fault (core dumped)
$ ulimit -s 8196
$ ./test
i[999][999] = 1998
