是每次运行都发生，还是在某个随机时刻只发生过一次？
Does it happen every time you run it, or just happened once at some random time?
我以前从没见过它失败。那是一次对 OpenSSL 的调用，我以为它永远不会失败，但我还是在那里放了个错误检查以防万一。我想不出它会怎么失败。也许是内存耗尽。
I've never seen that fail before. It's a call to OpenSSL that I assumed would never fail, but I put an error check there just in case. I can't imagine how it would fail. Out of memory maybe.
代码是：
The code is:
key.h:
key.h:
EC_KEY* pkey;
EC_KEY* pkey;
pkey = EC_KEY_new_by_curve_name(NID_secp256k1);
if (pkey == NULL)
throw key_error("CKey::CKey() : EC_KEY_new_by_curve_name failed");NID_secp256k1 是个常量。
NID_secp256k1 is a constant.
