Urgh. Somebody is to blame for that ugliness, but certainly not you. If it gets in, I suggest you add a comment to explain that. But this is worrying: elsewhere in the code, CRYPTO_get_locking_callback() is tested and an array is mallocated if it is null: that looks like a leak. I think part of that code needs to be changed to test the array itself instead of the callbacks. Regards, -- Nicolas George
