COM application hangs when you call CoCreateInstance from DllMain SYMPTOMS When you call the CoCreateInstance function from the DllMain function, the Component Object Model (COM) application hangs. CAUSE CoCreateInstance may start a thread that tries to call the DllMain function of all dynamic-link libraries (DLLs) that exist in the process by passing a DLL_THREAD_ATTACH value. Because the call originates from DllMain, and because DllMain is not a reentrant function, the call to CoCreateInstance never returns. RESOLUTION To resolve this problem, do not call CoCreateInstance from DllMain. You can move the call to an initialization function or to any other function that is called later. STATUS This behavior is by design. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue19790> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
