You need to remove the #if ENABLE(OILPAN). (Note that you need to keep
m_emulatedStencilBuffer.clear().)

Done.

     // This render buffer (heap) object must finalize itself.
     m_emulatedStencilBuffer.clear();
 #endif
     // Always call detach here to ensure that platform object deletion
     // happens with Oilpan enabled. It keeps the code regular to do it
     // with or without Oilpan enabled.
     //
     // See comment in WebGLBuffer's destructor for additional
     // information on why this is done for WebGLSharedObject-derived
     // objects.
