mem check hangs by mutex lock

We're using Valgrind 3.13 to check memory leak issues, and some test cases randomly hangs when it exit

We do see 2 kind of hangs, the 1st one seems happen more frequently, and hangs @ pthread_mutex_lock, the 2nd one hangs @ tls_get_addr_tail, please see attached file

Comment 2 Julian Seward 2018-09-03 07:11:26 UTC 
Statistically speaking, this is most likely to be a (locking)
bug in your program.  You run it with --tool=helgrind to get
more information.
Comment 3 Julian Seward 2018-09-03 07:12:23 UTC 
Closing as invalid.  If you have more information that suggests
it's really a bug in Valgrind -- including a small test case --
then please feel free to reopen.
