Out of memory crash decoding 16MB HEIF image

[larsxschneider]

I am using photoview which is importing HEIC/HEIF images with libheif v1.12.0 and I get the following error processing a HEIF image on machine with 4x32 bit ARM CPUs and 8GB of RAM (~4GB are usually free). What is special about this image is that it is a panorama image created on the iPhone 11 Pro with a file size of 15.8 MB (15,769,902 bytes) and an image size of 16382 × 3794 pixels.

runtime: out of memory: cannot allocate 251658240-byte block (863109120 in use)
fatal error: out of memory
