我正在 omnet++ & veins(v2.0-rc1) 下进行网络模拟，为此我实验了 4 个场景，两个场景都重复 20 次。
在模拟具有共同功能 (ack) 的第 3 和第 4 种场景时，我遇到了一些错误(我猜这是内存分配错误)。
对于相关的模拟，它正常启动并执行了几次重复但之后失败了(例如，它在第 4 个场景的第 5 次重复时失败)，输出如下:
0: *** glibc detected *** ./veins: free(): invalid next size (fast): 0x00007fff74bff590 *** 0: ======= Backtrace: ========= 0: /lib/x86_64-linux-gnu/libc.so.6(+0x76aa6)[0x2aeb29d1faa6] 0: /lib/x86_64-linux-gnu/libc.so.6(cfree+0x6c)[0x2aeb29d2484c] 0: /nfs/homes/hc.arslan90/mixim/mixim/examples/veins/../../out/gcc-release/src/modules/libmiximmodules.so(_ZN9ProphetV220executeInitiatorRoleEsP7Prophetl+0x6f4)[0x2aeb287ce334] 0: /nfs/homes/hc.arslan90/mixim/mixim/examples/veins/../../out/gcc-release/src/modules/libmiximmodules.so(_ZN9ProphetV214handleLowerMsgEP8cMessage+0x4b6)[0x2aeb287d0996] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppsim.so(_ZN11cSimulation10doOneEventEP13cSimpleModule+0xb0)[0x2aeb290135a0] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppcmdenv.so(_ZN6Cmdenv8simulateEv+0x170)[0x2aeb28a6f620] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppcmdenv.so(_ZN6Cmdenv3runEv+0x360)[0x2aeb28a6fba0] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppenvir.so(_ZN9EnvirBase3runEiPPcP14cConfiguration+0x13c)[0x2aeb28ca763c] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppenvir.so(_Z18setupUserInterfaceiPPc+0x55f)[0x2aeb28ca507f] 0: /home/dist/hc.arslan90/omnetpp-4.2/lib/liboppenvir.so(evMain+0x50)[0x2aeb28ca5d30] 0: /lib/x86_64-linux-gnu/libc.so.6(__libc_start_main+0xfd)[0x2aeb29cc7eed] 0: ./veins[0x402f21]
为了调试错误，我在这个命令中使用了 valgrind :
valgrind --tool=memecheck ./veins (with veins is the current binary of my simulation)
但似乎所有返回的错误都与我的代码无关(因为我对之前运行良好的代码做了同样的事情并且我得到了相同的输出)
编辑这里是Valgrind的输出

RUNTIME ERROR. A cRuntimeError exception is about to be thrown, and you requested (by setting debug-on-errors=true in the ini file) that errors abort execution and break into the debugger.
You should now probably be running the simulation under gdb or another debugger. The simulation kernel will now raise a SIGABRT signal which will get you into the debugger. If you are not running under a debugger, you can still use the core dump for post-mortem debugging. Once in the debugger, view the call stack (in gdb: "bt" command) to see the context of the runtime error.
<!> Error in module (cCompoundModule) scenario (id=1) during network setup: Class "ObstacleControl" not found -- perhaps its code was not linked in, or the class wasn't registered with Register_Class(), or in the case of modules and channels, with Define_Module()/Define_Channel().
TRAPPING on the exception above, due to a debug-on-errors=true configuration option. Is your debugger ready?

有人可以帮助识别错误吗？
注意:错误的代码引入了一个特定的数据结构，它是一个 std::map，它包含一个 std::set 作为值
最佳答案
您将需要使用相同的命令行参数启动模拟调试(或内存检查)运行；否则，将不会加载任何模型库，您的仿真也不会执行。
请注意，无论您如何启动模拟的调试或内存检查运行，您都应确保在 Cmdenv 中运行它。 (命令行环境)而不是 Tkenv .不仅您的仿真执行速度更快，您还可以确保所有警告都与您的仿真模型相关，而不是 GUI 和各种 GUI 库。您可以通过附加 -u Cmdenv 来完成此操作到命令行或(在 IDE 中)通过编辑模拟的运行配置并选择用户界面:命令行。
如果您从命令行运行模拟，只需在您通常执行的 opp_run 前加上前缀或您的模拟二进制文件(例如 ./veins )与 gdb --args (运行调试器)或 valgrind --tool=memcheck (运行内存检查器)。一个示例命令行可能是 <strong>/usr/bin/valgrind --tool=memcheck</strong> opp_run -l../../src/veins -n../../src/veins;. -u Cmdenv (添加了粗体文本)。
如果您想从命令行运行模拟，但当前使用的是 OMNeT++ IDE，您可以快速检查运行模拟时使用了哪些命令行参数。运行模拟时，在控制台 View 中观察输出。输出可能以 OMNeT++ Discrete Event Simulation 开头.在输出的开头附近，您还会发现以 $ 开头的两行.这些是 IDE 用于运行模拟的确切命令。
如果您想从 OMNeT++ IDE 运行模拟，请注意它还具有内置功能，可以在调试器或内存检查器中运行模拟。要在任一模式下运行模拟，请右键单击模拟的 .ini 文件(例如 omnetpp.ini，然后选择 Debug As(对于 gdb)或 Profile As(对于 valgrind)，然后是 OMNeT++ Simulation。运行模拟后，您可以在一个文件中找到 valgrind 的输出新的 Valgrind View 。
