32位windows下可以运行的程序在64位linux下报错

filt.c在32位windows code:blocks 10.05下运行无任何异样。

传到64位linux下，gcc -Wall filt.c -o main编译无任何错误；程序可以跑出所有结果，

和

windows下一样。

但是运行到free语句时报错：

typedef struct CCDS_ {

long int start[15000], end[15000];

} CCDS;

main() {

CCDS *ccds[25];

for(i=1; i<25; i++) {

if((ccds[i]=(CCDS *)malloc(sizeof(CCDS))) == NULL) {

printf("malloc ccds failed");

exit(1);

}

}

.....

for(i=1; i<25; i++) {

free(ccds[i]);

ccds[i] = NULL;

}

.....

}
