From b895abced91e6dcedf6c580ea3e51befc5c757c1 Mon Sep 17 00:00:00 2001 From: Paul Eggert Date: Sat, 2 Apr 2011 22:41:46 -0700 Subject: * alloc.c (mark_object_loop_halt, mark_object): Use size_t, not int. Otherwise, GCC 4.6.0 optimizes the loop check away since the check can always succeed if overflow has undefined behavior. --- src/alloc.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'src/alloc.c') diff --git a/src/alloc.c b/src/alloc.c index 07f1caae46..54c4760aba 100644 --- a/src/alloc.c +++ b/src/alloc.c @@ -5221,7 +5221,7 @@ int last_marked_index; links of a list, in mark_object.
