Hello again, We've made some progress with our tests. As it turns out, the main problem was with the call to ENGINE_finish, which we eliminated from our code for now.
Now we seem to be facing a new issue that comes up when a wrong PIN is entered and then the card is removed from the reader. After that, we can no longer do anything with the card after it is re-inserted. Not even by cleaning and reloading all the ENGINE-related functions. Would anyone have any hints on that?
