Re: Static lib and lua5.1.dll (crash on lua_close_())

I'm not sure exactly what bjam uses, however I can see one difference in
the way you have compiled your dll and the Lua dll.

/MT and /MTd are different, both pull in a multi-threaded CRT dll,
however /MTd pulls in the debug version.  So what happens is you have
two separate runtimes being used, and nasty things happen when for
example, memory is allocated in one, and free'd in the other etc.

Whatever bjam does will have to be the same too.

Hope that's the bug found! :-)
