From 107b8a922a9f72bae8d066549c675062bee0897f Mon Sep 17 00:00:00 2001 From: Ulrich Drepper Date: Mon, 14 Aug 2006 22:16:14 +0000 Subject: [BZ #1996] 2006-08-14 Ulrich Drepper [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. --- libio/memstream.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'libio/memstream.c') diff --git a/libio/memstream.c b/libio/memstream.c index 742da740ef..877383f3a8 100644 --- a/libio/memstream.c +++ b/libio/memstream.c @@ -83,7 +83,7 @@ open_memstream (bufloc, sizeloc) new_f->fp._sf._sbf._f._lock = &new_f->lock; #endif - buf = malloc (_IO_BUFSIZ); + buf = calloc (1, _IO_BUFSIZ); if (buf == NULL) return NULL; INTUSE(_IO_init) (&new_f->fp._sf._sbf._f, 0); -- cgit v1.2.3
