The zlib.compress() function crashes when the data size is greater than 102

[epeios-q37]

Hello Pierre,

Following code:

import zlib

print(zlib.compress(bytearray((0,) * 102))) # Works

print(zlib.compress(bytearray((0,) * 103))) # FAILS

displays under Brython (version 3.14.3 but also the development one):

b'x\x9cc\xa0\x0b\x00\x00\x00f\x00\x01'
Traceback (most recent call last):
  File <string>, line 5, in <module>
    print(zlib.compress(bytearray((0,) * 103))) # FAILS

    return bytes(compressor.compress(data)+compressor.flush())

and under Python:
