--- Comment #42 from caulier.gil...@gmail.com --- Here with sqlite, the crash is not reproducible. I compiled OpenCV3 myself and uninstalled openCV2 before, to prevent binaries mix of the library. Using valgrind reduce execution speed as you have seen. The program is executed in a "VM" like which check all memory allocation and use. If the crash is due to a race condition as i suspect, you will not able to reproduce it. This is why i would to add a mutex is the critical section of the OpenCV call code to be sure that method is not called more than one time by separated threads. But as you say that crash is also reproducible just when tagging face as well. perhaps the problem is in OpenCV as well... I don't know.... This is why a check with OpenCV2 can be interesting to do.
