Exception: 9key_error error

[bitcoin2paysafe]

Today, I've got an error message:

Exception: 9key_error
CKey::CKey(); EC:KEY_new_by_curve_name failed
bitcoin in ThreadBitcoinMiner()

Console:

terminate called after throwing an instance of 'key_error'
  what():  CKey::CKey() : EC_KEY_new_by_curve_name failed
Aborted


I hope that isn't a buffer overflow. Have anybody this error message too?

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.
