EXC_BAD_ACCESS in M13ProgressViewImage

[ghost]

Hi! Using iPad Air 2 iOS 11.1 I get EXC_BAD_ACCESS in M13ProgressViewImage.m at this line //Convert to grayscale using luma coding: http://en.wikipedia.org/wiki/Grayscale#Converting_color_to_grayscale uint8_t gray = (uint8_t)(0.3 * rgbaPixel[RED] + 0.59 * rgbaPixel[GREEN] + 0.11 * rgbaPixel[BLUE]); by updating the progress of an image frequently (as the content downloads)

Even I have the same issue. Can someone help ASAP?
