You are forcing a condition that is prohibited by MSDN:

It is safe to call other functions in Kernel32.dll, because this DLL is
guaranteed to be loaded in the process address space when the entry-point
function is called. It is common for the entry-point function to create
synchronization objects such as critical sections and mutexes, and use TLS.
Do not call the registry functions, because they are located in
Advapi32.dll. If you are dynamically linking with the C run-time library, do
not call malloc; instead, call HeapAlloc.

Calling imported functions other than those located in Kernel32.dll may
result in problems that are difficult to diagnose. For example, calling
User, Shell, and COM functions can cause access violation errors, because
some functions in their DLLs call LoadLibrary to load other system
components. Conversely, calling those functions during termination can cause
access violation errors because the corresponding component may already have
been unloaded or uninitialized.
