Another failure on test_zlib on the same buildbot: build 30

I already noticed some failures on test_mmap: build 8, 25 and 36

Issue #11738?

test_zlib failure is on zlib.crc32(mmap.mmap(...)) with a mapping bigger than 4 GB:
----------------------
# Issue #10276 - check that inputs >=4GB are handled correctly.
class ChecksumBigBufferTestCase(unittest.TestCase):
 def setUp(self):
 with open(support.TESTFN, "wb+") as f:
 f.seek(_4G)
 f.write(b"asdf")
 with open(support.TESTFN, "rb") as f:
 self.mapping = mmap.mmap(f.fileno(), 0, access=mmap.ACCESS_READ)
 def tearDown(self):
 self.mapping.close()
 support.unlink(support.TESTFN)
 @unittest.skipUnless(mmap, "mmap() is not available.")
 @unittest.skipUnless(sys.maxsize > _4G, "Can't run on a 32-bit system.")
 @unittest.skipUnless(support.is_resource_enabled("largefile"),
 "May use lots of disk space.")
 def test_big_buffer(self):
 self.assertEqual(zlib.crc32(self.mapping), 3058686908) <~~~ HERE
 self.assertEqual(zlib.adler32(self.mapping), 82837919)
----------------------
It looks to be related to #11277 (and #10276).

This issue is a duplicate of #11277.
