Help Deadlock analysis

The Deadlock occurs in my application when initialization of local static variable happens in the function called from DLLMain Entry point with param DLL_THREAD_DETACH.

Below is Windbg analysis

This is usually caused by another thread holding the loader lock.

Following are the Locks Held.

Please give you comments to understand what might have caused the deadlock. Note: the moment i make the static variable as non static the problem disappears this in context of example posted in forum Deadlock occurs in Function Scoped Static variables (Thread Unsafe in VC++)

In short, what caused the deadlock is that you did something non-trivial in DllMain.
