--- Comment #1 from Dennis <dkorpel@live.nl> ---
Removing the Phobos dependency:
```
static import core.math;

pragma(inline, true)
double sqrt(double x) @nogc @safe pure nothrow { return core.math.sqrt(x); }

extern(C) void main()
{
   double d = 9007199515875288.;
   auto r1 = cast (ulong) sqrt(d);
   auto r2 = cast (long) sqrt(d);
   assert (r1 == r2);
}
```

It doesn't happen when calling core.math.sqrt directly, it looks like the problem manifests because of the inliner:

```
// output of -vcg-ast
extern (C) extern (C) void main()
{
    double d = 9.0072e+15;
    ulong r1 = cast(ulong)((double x = d;) , sqrt(x));
    long r2 = cast(long)((double x = d;) , sqrt(x));
    assert(r1 == cast(ulong)r2);
    return 0;
}
```

It casts the comma expression to long/ulong, which may trip up the code generator.
