将 gcc 升级到 5.4.0 后，cppunit 抛出 std::bad_alloc

Question

我最近用 GCC 5.4.0 更新了我的 Gentoo Linux PC。

我还重新编译了所有依赖于 gcc 的包（gcc 升级指南中提到了 gentoo）。

大多数程序运行良好，但是我使用 cppunit 的测试在开始前抛出 std::bad_alloc。

一开始以为是cppunit更新的版本有问题，所以降级到之前的版本，问题依旧

每当我开始任何测试时，应用程序都会立即抛出：

terminate called after throwing an instance of 'std::bad_alloc'
  what():  std::bad_alloc

我在 gdb 中启动了应用程序并打印了调试回溯：

测试文件本身没有问题，因为我没有对它做任何修改，而且很多测试都运行了很长时间。

查看堆栈跟踪后，我很好奇第 12 帧发生了什么：__x=std::**__cxx1998**::vector of length **-2199020260704**, capacity **-2199020259433** = {...} 为什么会有cxx1998？长度和容量看起来都很疯狂（未初始化？）。

TestSuiteBuilderContext.h:29:

void 
TestSuiteBuilderContextBase::addTest( Test *test )
{
  m_suite.addTest( test ); //line 29
}

TestSuite.cpp:

/// Adds a test to the suite. 
void 
TestSuite::addTest( Test *test )
{ 
  m_tests.push_back( test ); 
}

Answer 1

我想出了部分解决方案。

编译选项貌似：

-D_GLIBCXX_DEBUG

导致问题。删除后 - 测试运行成功。
