      I have a Qt program that uses QPixmap to cyclically load some high-resolution images. The image size is 3150×4724 with 32-bit depth, loading one every 5~20 seconds. It crashes on certain Windows 10 systems! Examining the dmp file reveals a large number of undefined memory blocks around 1MB in size. Using Windbg to inspect the memory block contents, I found ICC-related configurations inside!
