tests/040.phpt failure on i686

[glensc]

the test results php engine needing to allocate over 4GiB memory, which obviously fails. can 32bit php even allocate that much memory?!

Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 4127195156 bytes) in msgpack-2.0.1/tests/040.php on line 18

the test should skip such platform, or whole test be dropped. what exactly is it testing?

$ export 'NO_INTERACTION=1' 'REPORT_EXIT_STATUS=1' 'MALLOC_CHECK_=2'
$ /usr/bin/make -j7 test 'PHP_EXECUTABLE=/usr/bin/php70' 'PHP_TEST_SHARED_SYSTEM_EXTENSIONS=pcre spl session' 'RUN_TESTS_SETTINGS=-q tests/040.phpt --show-out'


Build complete.
Don't forget to run 'make test'.
