BTW, I _think_ the reason I see the crashes and you don't is because I
have the smart card software AND I've enabled that registry key to
disable loading the CAPI library. So, for me, SSL_CTX_new() calls
ENGINE_by_id() for the CAPI engine, which fails, so then
ENGINE_load_builtin_engines() gets called (for the second time).

I think you don't see the crashes because you don't call
ENGINE_load_builtin_engines() twice. You could force this to happen
by setting eng=NULL right after the first call to ENGINE_by_id(). I
_think_ this will cause the SSL to re-initialize all the engines,
which is safe for well-behaved engines, but not for the GOST engine.
Not 100% sure though.
