Please take a look at this and ensure that the benchmark code is using D correctly. I did notice this:"I updated the ldc D compiler earlier today (incidentally, as part of upgrading my system with pacman -Syu), and now it doesn't compile at all. It was previously compiling, and ran at around 90% the speed of C++ on ARM."
Sigh.
