Multiple FEC decoders interfere with each other

[mhostetter]

The JIT-compiled decoders only use the finite field arithmetic from the first code.

Reproducer

import numpy as np

import galois

print("BCH 1")
bch_1 = galois.BCH(1023, 983)
message = galois.GF2.Random(bch_1.k).view(np.ndarray)
codeword = bch_1.encode(message)
decoded, N_corrected = bch_1.decode(codeword, errors=True)
print(N_corrected)

print("BCH 2")
bch_2 = galois.BCH(2047, 1992)
message = galois.GF2.Random(bch_2.k).view(np.ndarray)
codeword = bch_2.encode(message)
decoded, N_corrected = bch_2.decode(codeword, errors=True)
print(N_corrected)

print("BCH 1")
bch_1 = galois.BCH(1023, 983)
message = galois.GF2.Random(bch_1.k).view(np.ndarray)
codeword = bch_1.encode(message)
decoded, N_corrected = bch_1.decode(codeword, errors=True)
print(N_corrected)

print("BCH 2")
bch_2 = galois.BCH(2047, 1992)
message = galois.GF2.Random(bch_2.k).view(np.ndarray)
codeword = bch_2.encode(message)
decoded, N_corrected = bch_2.decode(codeword, errors=True)
print(N_corrected)

Actual

$ python3 .\test_bch.py
BCH 1
0
BCH 2
-1
BCH 1
0
BCH 2
-1

Expected

$ python3 .\test_bch.py
BCH 1
0
BCH 2
0
BCH 1
0
BCH 2
0
