What about using ref int[2] instead?

I just tested with your code modifying the signature and it works:

[steves at steveslaptop testd]$ cat bug3604.d
 extern(C) int tttc(ref int[2] x);
 void main() {
        int[2] input;
           tttc(input);
 }

[steves at steveslaptop testd]$ cat bug3604c.c
#include <stdio.h>

int tttc(int x[2]) {
    printf("just in C\n");
    printf("x=%p\n", x);
    printf("x[0]=%d\n", x[0]);
    printf("x[1]=%d\n", x[1]);
    printf("back from C\n");
}
[steves at steveslaptop testd]$ gcc -c bug3604c.c
[steves at steveslaptop testd]$ ../dmd2.037/linux/bin/dmd bug3604.d bug3604c.o 
[steves at steveslaptop testd]$ ./bug3604
just in C
x=0xbffa06e0
x[0]=0
x[1]=0
back from C

I think this better captures the correct signature than what I suggested in the
post.
