我试图使一个Python程序接口与不同的崩溃进程(这是我的手)。不幸的是，我正在使用的程序甚至不会可靠地崩溃!所以我想做一个快速的c++程序，它会故意崩溃，但我不知道最好和最短的方法来做到这一点，有人知道在我的
int main() {
crashyCodeGoesHere();
}
使我的c++程序可靠地崩溃

答案是平台特定的，取决于你的目标。但这里是Mozilla Javascript崩溃函数，我认为这说明了很多挑战，使这个工作:
static JS_NEVER_INLINE void
CrashInJS()
{
/*
* We write 123 here so that the machine code for this function is
* unique. Otherwise the linker, trying to be smart, might use the
* same code for CrashInJS and for some other function. That
* messes up the signature in minidumps.
*/
#if defined(WIN32)
/*
* We used to call DebugBreak() on Windows, but amazingly, it causes
* the MSVS 2010 debugger not to be able to recover a call stack.
*/
*((int *) NULL) = 123;
exit(3);
#elif defined(__APPLE__)
/*
* On Mac OS X, Breakpad ignores signals. Only real Mach exceptions are
* trapped.
*/
*((int *) NULL) = 123; /* To continue from here in GDB: "return" then "continue". */
raise(SIGABRT); /* In case above statement gets nixed by the optimizer. */
#else
raise(SIGABRT); /* To continue from here in GDB: "signal 0". */
#endif
}
其他回答
*( ( char* ) NULL ) = 0;
这将产生一个分割错误。
我唯一的闪光是abort()函数:
它以异常的程序终止终止进程。它生成SIGABRT信号，默认情况下，该信号导致程序终止，并向主机环境返回一个不成功的终止错误代码。程序终止时不执行自动或静态存储持续时间对象的析构函数，也不调用任何atexit(在程序终止前由exit()调用)函数。它从不返回调用者。
abort()函数可能是最好的选择。它是C标准库的一部分，被定义为“导致异常程序终止”(例如，致命错误或崩溃)。
void main()
{
int *aNumber = (int*) malloc(sizeof(int));
int j = 10;
for(int i = 2; i <= j; ++i)
{
aNumber = (int*) realloc(aNumber, sizeof(int) * i);
j += 10;
}
}
希望它崩溃。欢呼。
