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?
