Crash in correct_reed_solomon_decode()

[burt2902]

First of all, thank you for this great project.

I have been experiencing random crashes of the program that is decoding a reed-solomon protected data. I have managed to narrow down the issue to correct_reed_solomon_decode(). Below is a code snippet that eventually results in a crash.
The smaller the PARITY, the faster the crash happens. 2 is really fast, 4 takes quite some time, but eventually crashes.

#define PAYLOAD_SIZE      4
#define PARITY_SIZE       2

void rs_crash()
{
    correct_reed_solomon *rs = correct_reed_solomon_create(correct_rs_primitive_polynomial_ccsds, 1, 1, PARITY_SIZE);
    uint8_t encoded[PAYLOAD_SIZE + PARITY_SIZE];
    uint8_t decoded[PAYLOAD_SIZE];

    while(1)
    {
        for(int n = 0; n < PAYLOAD_SIZE + PARITY_SIZE; n++)
            encoded[n] = rand() % 256;
        correct_reed_solomon_decode(rs, encoded, PAYLOAD_SIZE + PARITY_SIZE, decoded); 
    }
}

Below crashes with just 2 calls to correct_reed_solomon_decode()

uint8_t encoded1[3] = {0x01, 0x02, 0x01};
uint8_t encoded2[3] = {0x01, 0x02, 0x02};
uint8_t decoded[2];

correct_reed_solomon *rs_dec = correct_reed_solomon_create(correct_rs_primitive_polynomial_ccsds, 1, 1, 1);

correct_reed_solomon_decode(rs_dec, encoded1, 3, decoded );
correct_reed_solomon_decode(rs_dec, encoded2, 3, decoded );  // crash
