Could you provide a patch?
I can ... a little static helper class is very helpful in this situation (I posted it some time ago to the list): //////////////////////////////////////// // class template static_ //////////////////////////////////////// template <typename T, typename OwnerT = void> struct static_ { T* operator -> () const { return &member; } static T* get() { return &member; } private: static T member; }; template <typename T, typename OwnerT> T static_<T, OwnerT>::member; /////////////// This way you can declare a global static instance of a type from anywhere in the code, i.e. in header files, because templates show a different behaviour for static members. The code could look like typedef boost::thread_specific_ptr<ptr_t> tld_t; static_<tld_t, X> tld_helper_static; tld_t tld_helper = tld_helper_static.get(); if (!tld_helper.get()) tld_helper.reset(new ptr_t); ptr_t &helper = *tld_helper; where X should denote any unique type (e.g. a private typedef) to distinguish this static instance of tld_t from other static instances of the same type.
