--- Comment #42 from caulier.gilles at 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.
