VULKANINFO

Same here. My mobile app is also affected. And it is confirmed on my PC.

According to the debugging result on Waifu2x ncnn, this is caused by the following lines of code in process_cpu():

if (channels == 4)
{
    memcpy(out.channel_range(3, 1), out_alpha_tile, out_alpha_tile.total() * sizeof(float));
}

And it only crashes on large RGBA images. (no crash confirmed on images probably smaller than 860x640)

The ncnn lib known to cause these crashes is 20220729. when compiled with version 20220721, it won't crash.
