  Hi libTiff community,

libTiff library crashes for a particular large chunky tiled YCbCr image when using the RGBA interface.

I tried this with your latest libTiff version (4.0.9) and earlier versions as well.

#include <tiffio.h>

    uint32 npixels=width*height;

    uint32* raster=(uint32 *) _TIFFmalloc(npixels *sizeof(uint32));
    TIFFReadRGBAImage(tif, width, height, raster, 0);

}

Please let me know if this can be fixed and in which release it will be fixed?
