Comment (by Tukra <list@…>):

 This line in tss_pe.cpp:

 __declspec(allocate(".CRT$XLC")) _TLSCB __xl_ca=on_tls_callback;

 causes a crash when statically linking boost.thread into a mixed-mode dll.
 From what I can tell this callback is only used for thread cleanup in exe
 builds. DLL builds will still get the same behavior via a dllmain hook:

 extern BOOL (WINAPI * const _pRawDllMain)(HANDLE, DWORD,
 LPVOID)=&dll_callback;

 So it seems safe to comment out the XLC hook if you are linking
 boost.thread into a dll.

 Also this is no longer a problem on Windows 10.
