Multiple assignment

[bearophile]

Is this program showing a bug in multiple assignments (DMD 2.052)?


void main() {
    int i;
    int[2] x;
    i, x[i] = 1;
    assert(x == [1, 0]); // OK

    int j;
    int[2] y;
    y[j], j = 1;
    assert(y == [0, 0]); // Not OK
}


At the end of the program I expect y to be [1,0] instead of [0,0].

Yet this C program with GCC:

#include "stdio.h"
int main() {
    int i = 0;
    int x[2] = {0, 0};
    i, x[i] = 1;
    printf("%d %d\n", x[0], x[1]);

    int j = 0;
    int y[2] = {0, 0};
    y[j], j = 1;
    printf("%d %d\n", y[0], y[1]);

    return 0;
}


has the same output as DMD:
1 0
0 0
