From 165635049a2f5af83efe2bd64b08e7b59e925e18 Mon Sep 17 00:00:00 2001 From: Peter Zhu Date: Wed, 21 Aug 2024 15:20:42 -0400 Subject: [PATCH] Don't use gc_impl.h inside of gc/gc.h Using gc_impl.h inside of gc/gc.h will cause gc/gc.h to use the functions in gc/default.c when builing with shared GC support because gc/gc.h is included into gc.c before the rb_gc_impl functions are overridden by the preprocessor. --- gc.c | 10 +++++----- gc/default.c | 6 +++--- gc/gc.h | 42 ++++++++++++++--------------------------- test/ruby/test_array.rb | 8 ++++---- 4 files changed, 26 insertions(+), 40 deletions(-) diff --git a/gc.c b/gc.c index 3a81642884..916b654e12 100644 --- a/gc.c +++ b/gc.c @@ -2901,7 +2901,7 @@ gc_ref_update_object(void *objspace, VALUE v) VALUE *ptr = ROBJECT_IVPTR(v);
