The biggest problem with mixing /MD and /MTd being that you are using two different C run-time libraries within the same application, although both are multi-threaded capable.
The two memory heaps are different, and so are the handle sequences for some types of handle allocations. You may even get handle values that are duplicated, but with completely different references within the run-time environments. As a result, if there isn't perfect layer separation at some stage you'll corrupt memory in unpredictable areas. Mixing run-times is a recipe for disaster, hence Dr Henson's suggestion.

OpenSSL by default is compiled with /MD if you don't change that and compile with /MTd you can get a runtime library conflict which can produce strange behaviour. Steve. -- Dr Stephen N. Henson.
