New issue 265 by rgovostes: Miscalculation of ByteMap kSize1 for small mmap
ranges
http://code.google.com/p/address-sanitizer/issues/detail?id=265
In sanitizer_allocator_internal.h, the computed kSize1 template parameter
used in the typedef of ByteMap can be zero if SANITIZER_MMAP_RANGE_SIZE is
not at least 64 GB. This causes the map1_ array to be of length 0.
Note that the same typedef in asan_allocator2.cc requires only a minimum of
4 GB due to a different value of kRegionSizeLog.
