【问题描述】：
我尝试在 Veins erlangen 示例中模拟 1000 辆汽车。但模拟器总是停止大约 700 辆车并显示错误消息。我可以模拟 500 辆汽车。为什么我不能模拟 1000 辆汽车？
运行时错误。即将抛出 cRuntimeError 异常，并且 您要求（通过在 ini 文件中设置 debug-on-errors=true ） 错误中止执行并进入调试器。
您现在应该在 gdb 或其他环境下运行模拟 调试器。模拟内核现在将发出一个 SIGABRT 信号，该信号 会让你进入调试器。如果您没有在 调试器，您仍然可以使用核心转储进行事后调试。 进入调试器后，查看调用堆栈（在 gdb：“bt”命令中）以 查看运行时错误的上下文。
模块中的错误 (Veins::TraCIScenarioManagerLaunchd) RSUExampleScenario.manager (id=6) 在事件 #21128，t=2112.7： std::bad_alloc: std::bad_alloc。
