 One final comment about compiling applications linked to the OpenSSL library.
 If you don't use the multithreaded DLL runtime library (/MD option) your
 program will almost certainly crash: see the original SSLeay description
 below for more details.
 program will almost certainly crash because malloc gets confused -- the
 OpenSSL DLLs are statically linked to one version, the application must
 not use a different one.  You might be able to work around such problems
 by adding CRYPTO_malloc_init() to your program before any calls to the
 OpenSSL libraries: This tells the OpenSSL libraries to use the same
 malloc(), free() and realloc() as the application.  However there are many
 standard library functions used by OpenSSL that call malloc() internally
 (e.g. fopen()), and OpenSSL cannot change these; so in general you cannot
 rely on CYRPTO_malloc_init() solving your problem, and you should
 consistently use the multithreaded library.
