* malloc/malloc.c (MALLOC_ALIGNMENT): Revert to (2 * SIZE_SZ) value. cvs/fedora-glibc-20060306T0720
The correct value differs only on powerpc32, and for now changing it there is causing more trouble than it's worth. * malloc/arena.c: Add compile-time sanity check on padding calculation. 2006-03-05 Jakub Jelinek <jakub@redhat.com> * malloc/arena.c (heap_info): Adjust the padding size if MALLOC_ALIGNMENT > 2 * SIZE_SZ.
