[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.
