Perhaps this is just due to some implementation details/limitation under the 
complex TSS implementation for static Boost.Thread under Win32.

I've put in some more time into studying the details of tss(_hooks|_pe|).cpp 
and I can only agree with you about that the problem should not occur.

As I mentioned the call stack looks a bit weird from the release build, 
which perhaps could indicate memory corruption somewhere else in the program 
(instead of symbol problems). Wild guess, but I'll still have to dig even 
deeper into the problem.
