I guess not. See the following code. int main() { int c; scanf("%d", &c); int arr[c]; int p; char arr2[c]; int another; printf ("Terrible, diff=%d, diff=%d\n", (char*)&c-(char*)&p, (char*)&p - (char*)&another); return 0; } Seems that compiler treats it int arr[c] as int *arr. I don't think it should compile. Thanks >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
