If you create a multithreaded Dll, and then load it in an application by LoadLibrary and free it again by FreeLibrary, the application will crash.
If you debug the application, you will get following debug output:

VERIFIER STOP 00000201: pid 0x688: unloading dll containing active critical section
0209CE1C : Critical section address
00424494 : Initialization stack trace. Use dds to dump it if non-NULL.
00352DF8 : DLL name address (use `du ADDRESS' to dump if not null)
02080000 : DLL base address

Steps to Reproduce:
Create a Multithreaded Dll.
Include the following lines into an application:


hDll = LoadLibrary("Name_of_dll.dll");

// This crashes the application

This error occurs under Windows XP, but not under Windows Me.
