[v8-users] WinCE/ARM memory leak after Context::New() in a thread

[neilh248]

Hi,

I have modified the standard platform-win32.cc to build under CE (a
few minor changes) and built an ARM v8 lib.

When I link to this I can create a global ObjectTemplate, create a new
Context from it and compile/run scripts fine provided I do this in the
main application thread.

If I create a thread via CreateThread() and run the same code I leak
~2.1mb for every thread I create. The thread appears to return
correctly and the HandleScope destructor is entered.

The code I'm using in the thread is:

   {
      Locker locker;
      Locker::StartPreemption(100);

      HandleScope handle_scope;
      Persistent<Context> context = Context::New(NULL, script_global);
      Context::Scope context_scope(context);

      t = GETTICKSMS;

      TryCatch try_catch;
      Handle<Script> script = Script::Compile(String::New(thread-
>code.c_str()));

      rv = !script.IsEmpty();
      if (!rv)
         {
         str.Format("JavaScript compilation error: %s",
script_extracterror(&try_catch).c_str());
         log_add("script_thread(): %s", str.c_str());
         }
      else
         {
         Handle<Value> result = script->Run();
         rv = !result.IsEmpty();
         if (!rv)
            {
            str.Format("JavaScript runtime error: %s",
script_extracterror(&try_catch).c_str());
            log_add("script_thread(): %s", str.c_str());
            }
         }
      context.Dispose();
      context.Clear();
      }

If I just leave the Locker and HandleScope the leak goes away.

Any ideas?

Thanks,


Neil
