主要是通过__dl_sym来hook，避免_dlerror_run申请内存导致malloc库死锁。不需要NO_PTHREAD_MUTEX_HOOK宏应该也是没问题的了。NO_PTHREAD_MUTEX_HOOK跟这个issue关系不大，主要解决没法调整动态库加载顺序导致找不到pthread_mutex_*符号的问题。 > 对于brpc中，为什么要去hack pthread中的mutex相关符号呢 hook pthread mutex是为了支持contention profiler和[worker潜在死锁问题的检测](https://github.com/apache/brpc/pull/2692)。 > 那是不是当我设置NO_PTHREAD_MUTEX_HOOK时，对pthread mutex的操作，可能会更快？ 没开contention profiler的情况下，只是多了一个判断和线程局部变量加减，性能应该没有差别的。 -- This is an automated message from the Apache Git Service.
