From a C++/JS benchmark

I'd like to know why the GCC back-end is able to produce a more efficient binary from the C++ code (compared to the D code), but now the problem is not large, as before.

It seems I've found a benchmark coming from real-world code that's a worst case for DMD (GDC here produces code about 237 times faster than DMD).
