NULL CWinApp pointer in release mode but not debug mode

[Ed Peddycoart]

When I compile my app in debug mode, it works fine. When I compile in Release mode, it crashes. In AfxWinMain, AfxGetApp() returns 0x00000000. The values of the arguments passed to AfxWinMain are

hInstance = 0x00400000
hPrevInstance = 0x00000000
lpCmdLine = ""
nCmdShow = 1

Any suggestions? I have gone through rules 1-3 in the article Why doesn't my project work in release mode? on this site but the suggested changes did not change the results.
