The dynamic array seems to be shared with all instances of a class:
class A {
int array1[] = [0]; // dynamic array
int array2[1] = [0]; // static array
}
int main(char[][] p) {
A a1 = new A();
A a2 = new A();
a1.array1[0] = 10;
std.stdio.writefln(a1.array1[0]); // write 10: OK
std.stdio.writefln(a2.array1[0]); // write 10: should be 0
a1.array2[0] = 20;
std.stdio.writefln(a1.array2[0]); // write 20: OK
std.stdio.writefln(a2.array2[0]); // write 0: OK
return 0;
}
So I think that the variable array1 is shared with the objects a1 and a2.

This isn't a bug.
An array, behind the scenes, is nothing but a pointer and a length.
So the dynamic array in your class gets initialized with a specific pointer and length, which is the same for all instances because the _literal_ is the same.
The correct thing to do here is initialize the dynamic array in the constructor, for example, by dup-ing it :)
