This is because the test tries to allocate (sysinfo.totalram * 9 / 10) in buffer objects and the remaining 10% of memory is not always enough for the Android system. After a discussion with Chris Wilson I have split this test into a "basic" and an "apperture-thrash" subtest, in the same way as gem_linear_blits. The basic test uses just two buffer objects and the apperture-thrash test is skipped if there is insuffiecient memory.
