Memory leak when images are encoded in the PNG format on a Windows Embedded CE 6.0-based device

You run an application that encodes an image in the Portable Network Graphics (PNG) format on a Windows Embedded CE 6.0-based device. However, a memory leak of 4 or 8 kilobytes (KB) occurs every time that the application calls the IImage::PushIntoSink method. If this method is called many times, an “out of memory” exception may occur.
