If you ever run into the following error while running a multithreaded application in C++ application which makes use of mutex's for synchronization
networkDataShareSyncApp: /usr/local/include/boost/thread/pthread/mutex.hpp:47: boost::mutex::~mutex(): Assertion `!pthread_mutex_destroy(&m)' failed. Aborted (core dumped)
gdb detailed stack trace for the same problem:
(gdb) bt #0 0x00000034594328a5 in raise () from /lib64/libc.so.6 #1 0x0000003459434085 in abort () from /lib64/libc.so.6 #2 0x000000345942ba1e in __assert_fail_base () from /lib64/libc.so.6 #3 0x000000345942bae0 in __assert_fail () from /lib64/libc.so.6 #4 0x0000000000404391 in boost::mutex::~mutex (this=0x608e80, __in_chrg=<value optimized out>) at /usr/local/include/boost/thread/pthread/mutex.hpp:47 #5 0x0000003459435da2 in exit () from /lib64/libc.so.6 #6 0x000000345941ece4 in __libc_start_main () from /lib64/libc.so.6 #7 0x00000000004036a9 in _start () (gdb)
Then the problem might be:
a) Either your main() thread/program is exiting without joining the threads, and one of the threads is still using/referencing to the mutex variable
b) You are trying to destroy/delete the mutex explicitly from one of your thread, while it is still being referenced/used from another thread. Attempting to destroy a locked mutex results in undefined behavior.
