  Ok, that makes sense. So, in my case, what do you think I have to
change in order to follow the rules?
I mean, I'm using a DLL release of libssh, and storing my wrapper into
another DLL (which uses a lot of other libraries like pcre, boost,
etc...). If the callback function of libssh2 asks to allocate memory for
that variable in MY dll, and then deallocates that memory in libssh2's
DLL. What options do I have? (apart of defining my own memory allocator).
