Hi! After some nightmare chasing a bug within my code I boiled it down to a dummy MFC MDI project including nothing else but <boost/thread/tss.hpp> the line static boost::thread_specific_ptr<void *> tld_helper; in InitInstance() triggers an "R6030 - CRT not initialized" error, but only on one single windows XP platform. The app runs fine on all others. If you have any idea what might have gone wrong, please give me a hint. I put some simplified code below. Excluding the init() line in boost::details::tss(boost::function1<void, void*>* pcleanup) removes the initializing error in the executable :-( best regards, Markus My compiler settings: Microsoft Visual Studio 2005 Version 8.0.50727.762 (SP.050727-7600) Microsoft .NET Framework Version 2.0.50727 Installed Edition: Professional [...] Microsoft Visual C++ 2005 77626-009-0000007-41492 Microsoft Visual C++ 2005 Microsoft Visual Studio 2005 Professional Edition - ENU Service Pack 1 (KB926601) Compiler flags: /Ox /Ob2 /Oi /Ot /I "D:\FEV-Data\Sourcen\cpp\VC8\Common\DLLs\boost_1_34_0" /D "WIN32" /D "_WINDOWS" /D "NDEBUG" /D "_CRT_SECURE_NO_DEPRECATE" /D "_MBCS" /FD /EHsc /MT /Yu"stdafx.h" /Fp"Release\MaximumCM_Dummy.pch" /Fo"Release\\" /Fd"Release\vc80.pdb" /W3 /nologo /c /TP /errorReport:prompt /bigobj /wd4996 Linker flags /OUT:"D:\FEV-Data\ExperimentalCode\WerleShowBug\Release\MaximumCM_Dummy.exe" /INCREMENTAL:NO /NOLOGO /LIBPATH:"d:\FEV-Data\Sourcen\cpp\VC8\Common\DLLs\boost_1_34_0\stage\lib" /MANIFEST /MANIFESTFILE:"Release\MaximumCM_Dummy.exe.intermediate.manifest" /DELAYLOAD:"OleAcc.dll" /DEBUG /PDB:"d:\FEV-Data\ExperimentalCode\WerleShowBug\release\MaximumCM_Dummy.pdb" /SUBSYSTEM:WINDOWS /OPT:REF /OPT:ICF /MACHINE:X86 /ERRORREPORT:PROMPT nafxcw.lib DelayImp.lib <snip> // WerleShowBug.cpp : Defines the class behaviors for the application. // #include "stdafx.h" #include "WerleShowBug.h" #include "MainFrm.h" #include "ChildFrm.h" #include "WerleShowBugDoc.h" #include "WerleShowBugView.h" // #include <boost/utility.hpp> #include <boost/function.hpp> #include <boost/thread/detail/config.hpp> #include <stdexcept> namespace boost { class BOOST_THREAD_DECL my_exception : public std::exception {}; namespace detail { class BOOST_THREAD_DECL tss // : private noncopyable { public: tss(boost::function1<void, void*>* pcleanup) { if (pcleanup == 0) { } try { // remove this code and it runs init(pcleanup); // } catch (...) { delete pcleanup; } } private: unsigned int m_slot; //This is a "pseudo-slot", not a native slot void init(boost::function1<void, void*>* pcleanup); }; template <typename T> struct tss_adapter { template <typename F> tss_adapter(const F& cleanup) : m_cleanup(cleanup) { } void operator()(void* p) { m_cleanup(static_cast<T*>(p)); } boost::function1<void, T*> m_cleanup; }; } // namespace detail template <typename T> class thread_specific_ptr // : private noncopyable { public: thread_specific_ptr() : m_tss(new boost::function1<void, void*>( boost::detail::tss_adapter<T>( &thread_specific_ptr<T>::cleanup))) { } thread_specific_ptr(void (*clean)(T*)) : m_tss(new boost::function1<void, void*>( boost::detail::tss_adapter<T>(clean))) { } ~thread_specific_ptr() { reset(); } T* get() const { return static_cast<T*>(m_tss.get()); } T* operator->() const { return get(); } T& operator*() const { return *get(); } T* release() { T* temp = get(); if (temp) m_tss.set(0); return temp; } void reset(T* p=0) { // T* cur = get(); // if (cur == p) return; // m_tss.set(p); // if (cur) m_tss.cleanup(cur); } private: static void cleanup(T* p) { delete p; } detail::tss m_tss; }; #ifdef BOOST_MSVC # pragma warning(pop) #endif } // namespace boost #ifdef _DEBUG #define new DEBUG_NEW #endif // CWerleShowBugApp BEGIN_MESSAGE_MAP(CWerleShowBugApp, CWinApp) ON_COMMAND(ID_APP_ABOUT, &CWerleShowBugApp::OnAppAbout) // Standard file based document commands ON_COMMAND(ID_FILE_NEW, &CWinApp::OnFileNew) ON_COMMAND(ID_FILE_OPEN, &CWinApp::OnFileOpen) // Standard print setup command ON_COMMAND(ID_FILE_PRINT_SETUP, &CWinApp::OnFilePrintSetup) END_MESSAGE_MAP() // CWerleShowBugApp construction CWerleShowBugApp::CWerleShowBugApp() { // TODO: add construction code here, // Place all significant initialization in InitInstance } // The one and only CWerleShowBugApp object CWerleShowBugApp theApp; // CWerleShowBugApp initialization BOOL CWerleShowBugApp::InitInstance() { // This one killes the app static boost::thread_specific_ptr<void *> tld_helper; // InitCommonControlsEx() is required on Windows XP if an application // manifest specifies use of ComCtl32.dll version 6 or later to enable // visual styles.
