stringstream运算符＆lt;＆lt;崩溃（malloc_consolidate）

Question

Program terminated with signal 11, Segmentation fault.

代码是：

...
       if (logger->isEnabledFor(Level::ALL)) {\
            std::ostringstream oss; \
            oss << message; \
            logger->forcedLog(Level::ALL, oss.str(), __FILE__, __LINE__); \
        } \
...

它说，ostringstream的运算符＆lt;＆lt;不是一个可重新进入的功能。是吗？

这应该是因为stringstream :: operator＆lt;＆lt;是非重入函数。
