它是每次运行时都会发生，还是只在某个随机时刻发生过一次？
我以前从未见过这里失败。这是一次 OpenSSL 调用，我原以为它永远不会失败，但为了以防万一，我还是在那里加了错误检查。我想象不出它会怎样失败。也许是内存不足。
代码是：
key.h: 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 是一个常量。

Does it happen every time you run it, or just happened once at some random time?
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.
The code is:
key.h: 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 is a constant.
