--- Comment #1 from Paul Floyd <pjfl...@wanadoo.fr> --- So I think what happens is that arena_malloc allocates requested size + alignment + overhead Then the small block up to the alignment boundary gets freed. Since the alignment was added to the arena_malloc size then even in the worst case there will be the original user requested size available. That means that "extra-heap" is made up of overhead and slop from rounding up the the alignment boundary. And from what I see the slop depends on what was allocated previously. Since libc++ and libstdc++ do different allocations the slop is different. Conclusion: I need to filter the extra-heap for these aligned allocations. -- You are receiving this mail because: You are watching all bug changes.
