Sorry, very tight deadlines. My project environment is very heavy - it is
not going to be easy to just drop new version of boost ... and creating
test in isolation will take time that I do not have - considering that I
have a workaround.

The pointed out issue seems different, because in my case there is no
unloading of the library, steps are:
1. run the process
2. create a thread
3. load a library - with thread specific ptr
4. access the pointer - crash
