	* 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.
