Ruby2.6.0-preview1とtrunkでnmatrixがコンパイルできない
Description
https://github.com/SciRuby/nmatrix
Ruby2.5.1 まではコンパイルできたのですが、Ruby2.6.0-preview1 および trunk(r63103) でコンパイルできませんでした。
trunk を使ってビルドしたときのログです。

これは nmatrix 側で何か対応が必要でしょうか？対応が必要であれば、どのような変更をすればよいのか教えてもらえないでしょうか？

r61843 以降、ALLOCA_N マクロの中で（利用可能なときには） RUBY_ALIGNOF マクロを利用するようになったことがきっかけのようです。
ただこれはきっかけというだけで、どちらかというと RUBY_ALIGNOF マクロが config.h の中に _Alignof の形で定義されていて、nmatrix のように C++ のプログラム中で用いる場合にも alignof にはなってくれないことの方がより根本的な原因のように見えます。

- Status changed from Open to Closed
Applied in changeset trunk|r63123.
Prefer alignof() over _Alignof()
to allow C++ programs include <ruby.h>. [Bug #14668]
Updated by shyouhei (Shyouhei Urabe) over 6 years ago
とりあえずstdalign.hをincludeするようにしてalignofを優先したのでtrunkご確認ください。
余談ですがC++の場合、allocaを使う必然性は皆無のはずです。普通に VALUE slice_argv[dim]; とかでいいはず。CもC99以降はそうです。Rubyがいまだにalloca使ってるのは古いCに固執してるから、という認識でいます。

trunk で試したところコンパイルが通るようになりました。
ありがとうございます！
余談も https://github.com/SciRuby/nmatrix に共有しておきます。
