Question

I try C++ Driver 3.1.2, the code still crashed in client deconstructor

My first recommendation would be to run your program under valgrind, or to build it with AddressSanitizer enabled and see if you get any interesting output when you run the instrumented binaries. — acm, Jan 29 '18 at 16:24
I notice that you are using C++ driver 3.2.0, which is currently an rc1 state, and not released. Can you let me know the exact git hash or tag that you are using? Also, can you see if you get the same problem if you downgrade to C++ driver 3.1.3? — acm, Jan 30 '18 at 15:56
Also, can you please include the rest of the code? You have this almost at an compilable state. If you include the header for MongoMgr and a simple mainline that calls it and exhibits the problem, then I can test locally without trying to re-create the missing parts of your code. — acm, Jan 30 '18 at 16:04
The complete MongoMgr is posted, sorry for any inconvenience. — zed, Jan 30 '18 at 17:12
I put together your code locally (I had to fake out the `m_confLib` bit, and it does not crash for me. Now, that doesn't mean anything! There could still be a bug in the driver. — acm, Jan 30 '18 at 20:13
Can you let me know which version of C Driver, C++ Driver and boost you are using? At least I can avoid this error, otherwise, I have to implement my own connection pool. Thanks. — zed, Jan 31 '18 at 04:44
I'd prefer we got to the bottom of this issue, if possible. Because there is either a serious but subtle bug in your code, and it would be unwise to proceed further in that condition, or there is a subtle bug in the driver code which must be figured out. I'm using C driver 1.9.2, C++ driver master, and boost 1.66. — acm, Jan 31 '18 at 13:30
Can you provide the CMake and build system invocation you used to build the driver, and the compile line for your application? Also, the output of ldd on your application binary would be helpful. This issue is starting to feel to me like a mismatch between library components, somehow. — acm, Jan 31 '18 at 13:33
CMake 3.7.1, gcc 7.2.1, CentOS 7.2, boost 1.5.3, output of ldd is posted. — zed, Jan 31 '18 at 15:52
How did you invoke CMake to configure the C++ driver build? How did you invoke the generated build system? — acm, Jan 31 '18 at 16:22
Thank you very much, @acm. I finally solved it. I got two way to fix this problem. The first solution is implemented my own connection pool and manage the connections like thread pool. The second one is compiling the boost again, because I saw your answer to other questioners, boost compiler should be same as my code, but my original boost installed by `yum`. I think that is the reason why my code crashed. Thanks again. — zed, Feb 01 '18 at 16:56

This line looks suspicious to me: m_ptrPool = boost::shared_ptr<mongocxx::pool>{uri};

Can you change that to m_ptrPool = boost::make_shared<mongocxx::pool>(uri);?

Thank you for reply, this line originally is m_ptrPool = boost::shared_ptr(new mongocxx::pool{*m_ptrDbUri}); I did that only for attach the uri. – zed Jan 29 '18 at 16:43
@zed please update the code in your question to reflect what you are actually running when you see the crash, or it is very difficult to help. Also, did you try valgrind or ASAN? – acm Jan 29 '18 at 22:30
Sorry for confusing you, the code is updated. When I run it under valgrind, the output mostly like gdb,`'Invalid read of size 8 at 0x5481926: mongocxx::v_noabi::client::~client()` . and `Process terminating with default action of signal 11 (SIGSEGV): dumping core` . no memory leak. Should I attacth all of them to you? – zed Jan 30 '18 at 03:21
Yeah, try running valgrind with `--track-origins=yes` so we see where that was allocated from, if at all, and then post the output in your question. – acm Jan 30 '18 at 14:42
Hi, @acm, the output of Valgrind is posted. Thank you. – zed Jan 30 '18 at 15:29
The solution is compile the boost and program with the same compiler. – zed Feb 01 '18 at 16:58
