           Summary: Bitfields are overwritten erroneously
           Product: D
           Version: D2
          Platform: Other
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD

struct S
{
    mixin(bitfields!(
        int, "a" , 32,
        int, "b" , 32
    ));
}

void main()
{
    S data;
    data.b = 42;
    data.a = 1;
    assert(data.b == 42); // fail
}

Looks like assigning fields at offsets < 32 bit clears fields at offsets >= 32
bit.
