From a119b9d146fea877acc1e9ba5df0702163ce917a Mon Sep 17 00:00:00 2001 From: kosaki Date: Sun, 10 Jul 2011 07:46:00 +0000 Subject: * vm_core.h (typedef struct rb_vm_struct): create a new 'inhibit_thread_createion' field. * thread.c (rb_thread_terminate_all): set inhibit_thread_creation. * thread.c (thread_s_new): don't permit to create new thread if the VM is under destruction. Otherwise evil finalizer code can make SEGV. [Bug #4992][ruby-core:37858] * bootstraptest/test_objectspace.rb: new test for this fix. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@32492 b2dd03c8-39d4-4d8f-98ff-823fe69b080e --- vm_core.h | 1 + 1 file changed, 1 insertion(+) (limited to 'vm_core.h') diff --git a/vm_core.h b/vm_core.h index cc450c5790..da912b5b60 100644 --- a/vm_core.h +++ b/vm_core.h @@ -285,6 +285,7 @@ typedef struct rb_vm_struct { VALUE thgroup_default; int running; + int inhibit_thread_creation; int thread_abort_on_exception; unsigned long trace_flag; volatile int sleeper; -- cgit v1.2.1
