@sdaoden(, @pitrou): Antoine proposes to skip the zlib "big buffer" (1 GB) test on 32 bits system. What do you think?
On 64 bits system, we check a buffer of 2 GB-1 byte (0x7FFFFFFF bytes). Is the test useful or not? What do we test?
Can you check if the test crashs on Mac OS X on a 32 bits system (1 GB buffer) if you disable F_FULLFSYNC in mmapmodule.c? Same question on a 64 bits system (2 GB-1 byte buffer)?
The most important test if to test crc32 & adler32 with a buffer bigger than 4 GB, but we cannot write such test in Python 2.7 because the zlib module stores buffer sizes into int variables. So the "big buffer" test of Python 2.7 test_zlib is maybe just useful (on 32 and 64 bits). Can we just remove the test?
