+
+ [BZ #4514]
+ * stdio-common/vfprintf.c (vfprintf): Don't shadow workstart variable,
+ reinitialize workend at the start of each do_positional format spec

+ (printf_unknown): Fix size of work_buffer.
+ * stdio-common/tst-sprintf.c (main): Add 3 new testcases.
+
+ * malloc/hooks.c (MALLOC_STATE_VERSION): Bump.
+ (public_sET_STATe): If ms->version < 3, put all chunks into

+ chunks.
+
+ * malloc/malloc.c [MALLOC_DEBUG]: Revert 2007-05-13 changes.
+ * malloc/hooks.c: Likewise.

+ * malloc/Makefile (CFLAGS-malloc.c): Revert accidental
+ 2007-05-07 commit.
+
+2007-05-18 Ulrich Drepper <drepper@redhat.com>
