大家好！
我正在尝试编译一个使用Boost.Test模块的代码，并且在使用某些参数时它似乎已经破坏了：每当我运行代码时，我都会遇到分段错误第一行到日志文件。自定义命名的日志文件存在，但为空，并且不会发出错误消息。
我的设置使用以下代码完成，之后初始化BOOST_GLOBAL_FIXTURE（成功）。如果我理解堆栈跟踪，则只有在开始遍历test_unit树时才会出现错误。
我在提升TRAC上打开了一张票：https://svn.boost.org/trac/boost/ticket/10943，但它甚至没有分配......
我正在运行CentOS 6.5，所以我的升级版本是1.41

我想，ostream是优化出来的 - 我所有的Eclipse GDB都给了我一个可能很时髦的地址：
std::ostream & unit_test_log_t::test_start::s_log_impl().stream() = @0x7fffffffc9a0

将一些BOOST_TEST宏从init_test_suite（）中移出后，我现在在
中出现了分段错误compiler_log_formatter::log_finish( std::ostream& ostr )
{
ostr.flush();
}
答案 0 :(得分：0)
在没有得到任何帮助之后，一些绝望的摆弄，它似乎工作。我不知道怎么做。
