Why Does std::random_device Produce Persistent Random Sequences in MinGW gcc4.8.1?

Persistent Random Sequence with std::random_device in MinGW gcc4.8.1

Despite its nomenclature, the std::random_device doesn't always generate truly random numbers. According to cppreference.com, "std::random_device may be implemented in terms of a pseudo-random number engine if a non-deterministic source... is not available to the implementation."

In the case of MinGW gcc4.8.1, it's likely that the implementation deliberately generates the same sequence each time to highlight the non-random nature of the output. This may be an intended design decision to emphasize the need for a more robust random number generator.

To address this issue and obtain genuinely random sequences, consider utilizing a alternative random device or seeding the pseudo-random number generator with a robust seed. This will enhance the unpredictability and randomness of the output.
