默认构造的std::regex_iterator是序列尾迭代器。在抵达最后匹配(std::regex_search返回false)后自增合法的std::regex_iterator时,它变得等于序列尾迭代器。进一步解引用或自增它会引发未定义行为。 典型的std::regex_iterator实现保有底层序列的开始和结束迭代器(两个BidirIt实例)、指向正则表达式的指针(constregex_...

解决方案: the cause is the google tests is looking for the generic regex.h but cmake used the regex.h from boost. and boost is not linked. I'm not sure how to fix it properly but renaming /usr/local/include/boost/regex.h temporarily to something else fix the problem. ...
