Update.
2004-11-13 Jakub Jelinek <jakub@redhat.com> * elf/rtld.c (print_statistics): Avoid segfaults if not all namespaces are used. Fix computation of num_relative_relocations on RELA architectures other than IA-64 and Alpha. 2004-11-13 Ulrich Drepper <drepper@redhat.com> * malloc/malloc.c (_int_free): Use munmap_chunk for handling mmaped memory.
