Linking TypeMock with NCover under Vista x64 crash

I recently stumbled over what seems like it could be a bug in TypeMock: When TypeMock 3.7.1 is linked with NCover 1.5.8 all .Net 2.0 processes started from VS2005 crashes. II7 will hang when I attempt to debug ASP.Net pages, the internal VS2005 web server also crashes and when pressing F1 the help pops up and closes again.

Running my ASP.Net app in IIS directly from Internet Explorer works fine. If I start the development server from the command prompt it does not crash. And if I launch the help from the start menu it does not crash either.

Unlinking NCover fixes the problem. I have not tested with other versions than TypeMock 3.7.1 and NCover 1.5.8. The x64 version of TypeMock is installed.
