Well, Patrick,
Actually the original post of this program referred to a[1449][0] element only. I guess it was a typo this time from Ankit (and that was the reason I did not bother to go through the program again). Anyway, Claudio's answer did clear most of the fog.
Cheers, Harsha.

hi
Hi,
well i had tried to enquire about this problem
i was not able to find the solution. i know it workds when i declare the array globally. i know if i use malloc it will work and i am using the same in my program
but this question is again in my mind that what could be the reason that it dosent work here on my system because last time when i asked this question on some sytem it was able to run which they said that they have less emory then that of my system
my system config.: redhat linux 9.0 +512 RAM this is what my terminal displays
[ankit@Ankit fft]$ cat try2.c
#include <stdio.h>
int main()
{
double a[1450][1450];
a[1450][0]=999.999;
You do not just have a stack problem : The upper bound is not 1450, but
1449, because the first index is 0.
So a[1449][0] has more chances to work correctly, but the problems generated by such a fault can be insidious and very difficult to discover, because the error can appear later in your program.
printf("%lf\n",a[1450][0]); return 0; } [ankit@Ankit fft]$ gcc try2.c [ankit@Ankit fft]$ ./a.out Segmentation fault [ankit@Ankit fft]$
i just want to know that if there is some problem related to stack how t oget rid of it
thanks
ANkit
