http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60931 --- Comment #5 from Anton Blanchard --- I think I see it: 19112 madvise(0xc21103, 4096, MADV_DONTNEED) = 0 That 4kB madvise(MADV_DONTNEED) gets rounded up to the system page size of 64kB and we end up covering still in use memory. The follo

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60931 --- Comment #2 from Anton Blanchard --- I agree, but when I tried this I found a few places that expect PageSize to be a compile time constant so it is not as trivial as I had hoped.

http://gcc.gnu.org/bugzilla/show_bug.cgi?id=60931 --- Comment #1 from Andrew Pinski --- This is going to be true on AARCH64 also where most distros are going to be using 64k pages (some might use 4k pages if they also support AARCH32). MIPS has many different page sizes too (4k, 8k, 16k, 32k, an
