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.
