I think i have found the problem,

the dll i used included the Managed Extensions for C++ projects. This cause the problem because Managed Extensions for C++ projects that are created as DLLs by default do not link to native C/C++ libraries such as the C run-time (CRT) library, ATL, or MFC and do not use any static variables (see http://support.microsoft.com/?scid=kb%3Ben-us%3B814472&x=5&y=4).  The testind DLL i wrote did not uses the managed extensions and therefore had no problems.

Maybe you should mention this pitfall in the boost thread documentation.

I use Boost Version 1.36.
Unfortunately the code is not easy to cut out, because of many dependencies. I will try to cut of all unneeded parts but this will take some time.

Unfortunately i get an error during the loading of the dll when i define a
boost::thread_specific_ptr within the dll. The dll compiles fines. If i want
to use the dll with the LoadLibrary command i get Error 193  "is not a valid
Win32 application".

The result is that everything works fine
(including boost::thread_specific_ptr ) untill i instantiate cetain objects.

Firstly, which version of Boost are you using, and with which compiler?

Secondly, there is clearly a bad interaction between these objects and boost::thread_specific_ptr. Please could you post some code that demonstrates the problem, so we can figure it out.
