GCC bug? Compiled code gives seg. fault

Hi,
I have a simple code which allocates static memory. When compiled
with gcc (GCC version, OS details are given below), the compiled code
gives a segementation fault where it should not.
The code is as follows (file "xxx.c"):
#include <stdio.h>
#include <string.h>
#include <math.h>
#include <stdlib.h>
#define MAX_DATA_LEN 60000
#define MAX_COLUMN_NOS 120
int main(int argc, char **argv)
{
char line[2001], *strptr;
float data[MAX_DATA_LEN][MAX_COLUMN_NOS];
float dat[MAX_DATA_LEN];
float mean, rms, err, max, min;
float sigma_max = 3.0, thresh;
return 0;
}
The output of "gcc -E xxx.c >| xxx.e" is attached at the end of this
message with blank lines removed from the output.
Details of the problem:
----------------------
(1) OS Used: RedHat 6.2 distribution of GNU/Linux
(2) Compiler used:
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/egcs-2.91.66/specs
gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)
(3) Symptoms of the problem:
(a) The compiled program gives a segmentation fault
(b) If the code is compiled with -O2, there is no segementation
fault
(c) If MAX_DATA_LEN in the above code is reduced to about 1700 or
so (exact number not know but reducing helps is known), the
problem disappears
(d) It's reported that this problem does not appear on Mandrake's
latest distribution of GNU/Linux using the same version of GCC
(e) If sigma_max in the above code is not initialized during it's
decleration is, the problem disappears
(f) If sigma_max is made static, the problem disappears
Could some one tell me if this is a bug in GCC of there is something
else that's wrong?
Regards,
sanjay
