--- Comment #56 from Evert Vorster <evert.vorster at yandex.com> ---
Now we are getting somewhere. 

I finally managed to compile a version of opencv that has tbb disabled.

With Maik's patch installed I was able to scan through 25% of my library before
I hit the bug of "MySQL server has gone away", so definitely have one issue
nailed down to opencv's use of tbb. 
I can try again with internal SQlite, and see if I can scan through my
collection completely. 

Since this version of opencv I have now is the contrib version, I will try
again to build with Gilles' patch. 

Looking back over the patches, which, if any, are recommended for me?
Do I file a bug report at OpenCV for the crashes in TBB? (I did a bit of
reading about it, and appears that the memory errors that valgrind reports is
because TBB uses their own scheduler and that can confuse valgrind)
