（標準C ++コンパイラでは、可能な限り長いエラーメッセージを生成する短いプログラムを、書くgcc、cl.exe、icc、またはclang）。

各エントリのスコアは、コンパイラが発行した最長のエラーメッセージの文字数です。ソースコードに含まれ、コンパイラによって引用された型は、単一の文字としてカウントされます。

不正行為

長い名前のテンプレートでは、テンプレート内のテンプレートをいつでも再定義できますが、創造的なものを期待しています。私は最後のルールでその一部を防止しようとしましたが、もちろんルールはより良くなる可能性があり、改善ができてうれしいです。

タグを編集しました。[kolmogorov-complexity] は少し伸びていることは認めますが、この場合は表現力があると思います。

たぶん、あなたは比率のために行くべきです：Error.message.length / code.length。

テンプレートのエラーメッセージは解読するのが楽しいです。このことを考慮：

#include <vector>
#include <algorithm>
int main()
{
    int a;
    std::vector< std::vector <int> > v;
    std::vector< std::vector <int> >::const_iterator it = std::find( v.begin(), v.end(), a );
}

gcc -c error.cpp（4.6.3）でコンパイルすると、330文字の最長行で15786バイトの出力が生成されます。

これは、C ++がポリモーフィックな再帰をサポートしているかどうかを確認したいときに発見しました（そして、明らかなように、サポートしていません）。Haskellのポリモーフィックな再帰の簡単な例を次に示します。

Prelude> let f :: (Show a) => a -> String; f x = show x ++ " " ++ f [x]
Prelude> f 0
"0 [0] [[0]] [[[0]]] [[[[0]]]] [[[[[0]]]]] [[[[[[0]]]]]] [[[[[[[0]]]]]]] [[[[[[[[0]] ...

ここでは、Haskellがインスタンス化するように動作する必要があります Show x、Show [x]、Show [[x]]、Show [[[x]]]、無限に。Haskellは、コンパイラーによって追加された(Show x) =>関数への暗黙的なパラメーターに変換することでf、次のようにします。

type Show a = a -> String

showList :: Show a -> [a] -> String
showList show []     = "[]"
showList show (x:xs) = '[' : show x ++ showItems xs where
    showItems []     = "]"
    showItems (x:xs) = ',' : show x ++ showItems xs

f :: Show a -> a -> String
f show x = show x ++ " " ++ f (showList show) [x]

C ++は、テンプレートのインスタンス化の深さを超えるまで、そのようなインスタンスを文字通り構築しようとすることでそれを行います。

多態性再帰で何を達成しようとしたのか説明できますか？HaskellとC ++の両方の例ではプロセスが無限であるため、実行時またはコンパイル時に発生するのは違いのみです。

— sukhmel

@sukhmelいいえ、Haskellは遅延しているため、コンパイルして実行します（デモ版として）

— cat

@cat私はそれが実行されないことを暗示していませんが、そのような実行は決して停止しないことを指摘しましたか？Althougは、Joeyが達成しようとしたことで、特定のテンプレートの場合に停止条件があったはずだと思うので、ポリモーフィックな再帰を試みる背後にあるアイデアについて疑問に思っていました。

次のコードは、私が一度遭遇した実際のエラーに基づいています。

template <int i>
void bar();

template <int i>
void foo()
{
    bar<i>();
    char baz[i];
}

template <int i>
void bar()
{
    foo<i-1>();
}


int main(void)
{
    foo<2000>();

    return 0;
}

（gccを使用）

かなり明白なテンプレートの再帰ですが、ftemplate-depth=100000この実行に使用したため、エラーは発生しません。エラーメッセージの実際のソースから来char baz[i];たときにエラーが発生しています、i -1に低下します。

約30分後、私は21,000のコンパイラエラー、300,000行のエラーメッセージ、およびコンパイラが使用する280メガバイトのRAMに座っています。そして、それは停止の兆候を示していません。

そのセグメンテーション違反のバグレポートを送ったのですか？

現在のLLVMバージョン（Apple LLVMバージョン8.0.0（clang-800.0.42.1））では、セグメンテーション違反は発生しません。私がまだ何かを提出すべきかどうかはわかりません-LLVMのメンテナーが古いバグを気にするのは疑わしいです。

#include<stdexcept>


int main(int argc,char** argv){
    std::array<double, 3> arr;

    arr[0] = 0; arr[1] = 1; arr[2] = 1;

    if (std::any_of(arr.begin(), arr.end(),

        throw std::invalid_argument("Geometry with bin width less or equal to zero");

    return f<0-1,p...>();
}

int main() {

82バイト：これはJoey Adamsのアプローチと同様に機能しますが、エラーメッセージは-ftemplate-depth（std::set<T>実際はであるためstd::set<T, std::less<T>, std::allocator<T>>）指数関数的に増加します。

の場合(x = -ftemplate-depth) >= 28、1460×3 ^x-27 + 269x-5381バイトのエラーメッセージ（gcc 7.2.0でコンパイル）があります。つまり、デフォルト設定（x = 900）では、理論的に約4.9×10 ⁴¹⁹バイトのエラーメッセージが出力されます。

returnステートメントがないと、エラーメッセージはコンパイルの最後にのみ生成されることに注意してください。（したがって、デフォルト設定ではメッセージを取得しません-最初にメモリが不足します。）

警告：このプログラムをコンパイルすると大量のメモリが消費されます。

#include<set>
template<class T>T f(T a){return f(std::set<T>());}int main(){f(0);}

使用してmapいるので、厳密にはもっと悪そうですstd::map<T,T>ですstd::map<T,T,std::less<T>,std::allocator<std::pair<T,T>>>ので、あなただけの2バイト以上のための5ウェイ再帰の代わりに3を取得します。

また、LLVMバージョン10.0.0（clang-1000.11.45.5）で検証され、追加のフラグはありません。で148,379バイト、-ftemplate-depth=13で423,572バイト-ftemplate-depth=14、およびで1,247,322バイトを生成しました-ftemplate-depth=15。mapバリアントは、深さ14で13,373,990バイト、深さ15で66,759,871バイトを生成します。

— nneonneo

Egads、Clangのデフォルトはです-ftemplate-depth=1024。これは、mapバリアントを含む10 ^ 713バイトの北のどこかを意味します。これはあなたが勝つことを意味すると思います...

これにより、GCC 5.2およびClang 3.6で無限の出力が生成されます（Clangでは-ferror-limit=0、GCCではデフォルト設定で動作します）。
