ntdll.dll is not found in POCO?

Question

When I use HTTPSClientSession to run a program, it crashes because:

NULL pointer: _pInstance [in file "c:\poco-1.4.3p1-all\util\include\poco\util\application.h,line 446]

Then, I traced the stack, and found that ntdll.dll was not loaded, which I doubted.

Any ideas why NTDLL looks like it's not loaded?
