[BZ #1996]
2006-08-14  Ulrich Drepper  <drepper@redhat.com>
	[BZ #1996]
	* libio/memstream.c (open_memstream): Allocate initial buffer with
	calloc.
	* libio/wmemstream.c (open_wmemstream): Likewise.
	* libio/strops.c: Pretty printing.
	(_IO_str_overflow): Clear uninitialized part of the new buffer.
	(enlarge_userbuf): New function.
	(_IO_str_seekoff): Call it if seek position is larger than current
	buffer.
	* libio/wstrops.c: Likewise.
	* libio/vasprintf.c: Add comment as to why we do not have to use
	calloc instead of malloc to allocate initial buffer.
	* libio/Makefile (tests): Add bug-memstream1 and bug-wmemstream1.
	* libio/bug-memstream1.c: New file.
	* libio/bug-wmemstream1.c: New file.
