This is not true for arm64 so MapAlignedPagesRandom returns = null when the last attempts are not in a validRange. Furthermore I cannot confirm that linuxes randomizes mmap'ed virtual addresses, so TryToAlignChunk works better there. --=20 You are receiving this mail because: You are on the CC list for the bug.
