Following code prints different result in 32/64 bit code in Windows.

import core.stdc.stdio : printf;
struct S
{
    this(this) { printf("postblit this = %p\n", &this); }
}
void main()
{
    S s;
    S[2] sa;
    S[2][] dsa = [[S(), S()]];
    {
        printf("---\n");
        dsa ~= sa;      // [1]
        printf("---\n");
        dsa ~= [s, s];  // [2]
    }
}

$ dmd -m32 run test.d
---
postblit this = 00431FE2
postblit this = 00431FE3
---
postblit this = 0018FE24
postblit this = 0018FE25
postblit this = 00431FE4
postblit this = 00431FE5

$ dmd -m64 run test.d
---
postblit this = 0000000001ED1FE2
---
postblit this = 000000000027F618
postblit this = 000000000027F619
postblit this = 0000000001ED1FE4

Both [1] and [2] should call postblit twice, regardless the pointer size.
