this code won't make dmd access violation:
static char[] hello()
{
        char[] result="";
        int i;
        for(;;i++)
           result ~= `abc`;
        return result;
}
void main()
{
        pragma(msg,hello());
}

the problem is intepret.c line 594, it assumes increment is an object which is
never null, while in this case, the loop doesn't have any increment statement.
So a quick fix is 
add to line 594
                if (!increment)
                        continue;
