The bug still exists if the the struct has a constructor and we're appending to
a dynamic array
-
struct Bug6052c {
int x;
this(int a) { x = a; }
}
static assert({
Bug6052c[] pieces = [];
for (int c = 0; c 2; ++ c)
pieces ~= Bug6052c(c);
assert(pieces[1].x == 1); // ok
assert(pieces[0].x == 0); // asserts
return true;
}());
-
x.d(10): Error: assert(pieces[0u].x == 0) failed
snipped
-
or filling the uninitialized portion of a dynamic array
-
static assert({
int[1][] pieces = [];
pieces.length = 2;
for (int c = 0; c 2; ++ c)
pieces[c][0] = c;
assert(pieces[1][0] == 1); // ok
assert(pieces[0][0] == 0); // asserts
return true;
}());
-
x.d(7): Error: assert(pieces[0u][0u] == 0) failed
snipped

A related test case which also fails, but involves static arrays rather than
structs:
bool bug6052b() {
int[][1] arr;
int[1] z = [7];
arr[0] = z;
assert(arr[0][0] == 7);
arr[0] = z;
z[0] = 3;
assert(arr[0][0] == 3);
return true;
}
static assert(bug6052b());
