gccをwindowsで使うならstd::random_deviceを使ってはいけない

More than 3 years have passed since last update.

gccのstd::random_deviceはwindowsではmt19937、linuxまたはosxでは/dev/urandomを使っています。
mt19937を使う場合、シードはtokenパラメータで決めます。
std::random_device("mt19937")ならシードは5489に固定され、
std::random_device("12345")ならシードは12345になります。
でもtokenを数値にすると一部のシステムで例外がスローされます。

結論からするとstd::random_deviceは使わないのが吉です。
最初からmt19937を使うか、自分でラッパー関数を書くかにするべきです。

ちなみにlibc++はrand_sを使っています。
