I believe this is due to the DLL loader lock mechanism.

Basically, you are not supposed to call anything that might (implicitly) load another DLL from the DllMain function.

Google for "dll loader lock". The first link, "Best practices for creating DLLs" is a Word document describing the problem in detail.
