carray data written with blosc2 and fletcher32 filters will fail fletcher32 checksum on read

[alasla]

tables is perfectly able to read blosc2:lz4 data from previous versions of tables. Previous versions were:
tables: 3.8
blosc2: 2.0.0

With newest tables and blosc2 releases, when I write, and then try to read a carray written with blosc2:lz4 and fletcher32 filters, I get a fletcher32 checksum error.

tables 3.9.2
blosc2 2.6.2
numpy 1.26.4

reproduction code

import tables
import numpy as np
import blosc2
print(tables.__version__)
print(np.__version__)
print(blosc2.__version__)

input_arr = np.array([[0, 1, 1], [1, 0, 1]], dtype='int8')
print(input_arr)

f = tables.open_file('/tmp/tables.h5', mode='w')
print(repr(f))

filters = tables.Filters(complevel=9, complib='blosc2:lz4', shuffle=False, fletcher32=True)
print(repr(filters))

arr = f.create_carray('/', 'data', tables.Int8Atom(), input_arr.shape, filters=filters, chunkshape=None, obj=input_arr)
print(repr(arr))

f.close()

f = tables.open_file('/tmp/tables.h5', mode='r')
print(repr(f))

n = f.get_node('/data')
print(repr(n))

n.read()

results in an exception at n.read():

Problems reading the array data.

Works fine if I use zlib instead of blosc2. With fletcher32 checksum off, I don't see any differences in the read array from the input array that would indicate the data had been corrupted by blosc2...

Let me know if I can provide any other data.
