Heavily reduced test-case (so the snippet might not make sense), originally from CairoD:

struct ItemRange
{
    @property int front() { return 0; }
}

void main()
{
    ItemRange range;
    foreach (index, element; range)
    {
    }    
}

Using DMD 2.055 on XP32. 
Removing index from foreach prevents the crash:

foreach (element; range) { }
