Now that we're using LLVM 2.5, we can stop always running the CFGSimplification pass. The pass was originally added as a workaround for a LLVM 2.4 bug where debug info would reference labels that have been optimized away.

extern(C) int printf(char*, ...);

class C
{
    int i;
    void p()
    {
        printf("%d\n", i);
    }
}

void main()
{
    printf("should print 4\n");
    C c = new C;
    c.i = 4;
    c.p();
    //delete c;
}
