安卓，C/C++；内存崩溃不会'；Eclipse Java调试器中不会发生这种情况 我正在调查一个Android C++代码崩溃，致命信号11，当一系列动作在一个循环中被占用大约4到7次，随机发生，但是总是有一个 GcFoFoLeloC免费< >之前。如果我在EclipseJava调试器中运行该应用程序，问题就会消失，但在拔下usb电缆后，问题又再次出现。问题发生在Eclipse本机应用程序调试器中，当然也发生在单独运行时。使用的C++库庞大且非常复杂，所以从10s的.a文件中构建。试图增加堆大小，但没有帮助。问题可能是多次释放内存，或者试图使用已释放的内存。使用双向JNI调用。C++的LIB是用Debug信息构建的，Eclipse本地应用程序调试器在崩溃发生时停止，但是调用堆栈没有显示有用的信息来定位问题。任何建议都是非常感谢的，因为我已经在这个问题上好几个星期了

编译所有内容以查看堆栈？这并不是很容易调试的。看起来C++要么是引用java堆内存，要么是无效的，要么反之亦然。地址非常高，看起来不像是随机地址。我猜可能是C重写了一个不再有效的内存地址，Java认为它拥有这个地址，并将其作为指针存储在空闲列表中。FWIW，四天前报道的以下问题可能与此有关：谢谢大家的想法。任何解释为什么在Eclipse java调试器中都是OK的？问题是C++中的，有些错误的代码被调用。没有工具可以直接帮助我定位问题。谢谢
