关于std::string在solaris 10下有时析构coredump?

断欲

我实现了一个打印日志的CDebugKit对象，以动态库方式提供。但是在solaris 10经常发生在std::string在析构中__unLink()时core掉，麻烦大家帮忙分析看看


操作系统为:Sun Microsystems Inc.   SunOS 5.10      Generic January 2005

出问题栈信息如下:

ff0a4180 void std::basic_string<char,std::char_traits<char>,std::allocator<char> >::__unLink() (1ca3134, 8041, f3d2c0, 1ca3138, 1ca3138, 0) + 80
