From f8aebc52b519ef4e9c0324d43d5dc87179ac0193 Mon Sep 17 00:00:00 2001 From: Max Kellermann Date: Sat, 7 Mar 2009 21:40:13 +0100 Subject: music_pipe: poison music_chunk.next The value of music_chunk.next is undefined for a chunk returned by music_pipe_shift(). For more pedantic debugging, poison the reference before returning the chunk. --- src/pipe.c | 5 +++++ 1 file changed, 5 insertions(+) diff --git a/src/pipe.c b/src/pipe.c index 320c5c3a3..076185d2a 100644 --- a/src/pipe.c +++ b/src/pipe.c @@ -88,6 +88,11 @@ music_pipe_shift(struct music_pipe *mp) assert(mp->size > 0); assert(mp->tail_r != &chunk->next); } + +#ifndef NDEBUG + /* poison the "next" reference */ + chunk->next = (void*)0x01010101; +#endif } g_mutex_unlock(mp->mutex); -- cgit v1.2.3
