pthread_cond_signal(&cond); // 激活一个等待该条件的线程 pthread_mutex_unlock(&lock); } 在这个示例中,condition_met是在多个线程间共享的条件变量,它通过互斥锁lock来保护其数据完整性。当条件不满足时,使用pthread_cond_wait函数让线程等待。直到另一个线程调用pthread_cond_signal更改条件并通知等待的线程。

看右下角可知,其崩溃在方法pthread_rwlock_wrlock中。而这正是因为我们删掉static_init()后 rwlock_t runtimeLock; rwlock_t selLock; mutex_t cacheUpdateLock; recursive_mutex_t loadMethodLock; 这四行代码没有执行引起的(因为对应的构造函数不能执行)。至此谜题终于解开了。
The second issue was that we had used the pthread attribute `PTHREAD_MUTEX_ERRORCHECK_NP`, which is – as its name suffix “`_NP`” suggests – not portable. And indeed it broke compilation under `libmusl`, since there it does not exist. This could also be fixed easily by just removi...
In the goblint-regression subset, CSeq-DR fails to analyse 10 programs due to unsupported pthread library functions, parsing issues, and other internal errors. The analysis turns out to be too expensive on 57 instances; 50 of these are specifically crafted examples with ten thousands threads on...
