Hi Yuan, I created a workaround for this problem on 22 Aug 2017 titled "reduce the need to reallocate the std::ostream buffer behind osg::Notify..." - link <https://github.com/openscenegraph/OpenSceneGraph/pull/314>: https://github.com/openscenegraph/OpenSceneGraph/pull/314
As it's only a few lines, I guess backporting to 3.2 will be rather simple. Regards, Laurens.
