            Bug ID: 27455
           Summary: malloc: fix calculation of aligned heaps in new_heap()
           Product: glibc
           Version: 2.33
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: malloc
          Assignee: unassigned at sourceware dot org
          Reporter: hu4i233 at gmail dot com
  Target Milestone: ---

In mallo/arena.c new_heap()

The aligned_heap_area added in 
https://sourceware.org/legacy-ml/libc-hacker/2004-03/msg00095.html
aimming at avoiding fragmenting address space seems not to work properly.

And I find that someone has already found this problem but it seems that the
bug isn't fixed:
