#422 Ufraw seg faults on Fuji GFX 50s raw files (RAF)

[Chris]

Ufraw seg faults on Fuji GFX 50s raw files (RAF). While this camera does not appear on the official supported camera list (ufraw nor dcraw), it does work when using dcraw (dcraw raf.RAF | cjeg jpeg.jpeg).

This is what I'm seeing:
$ ufraw-batch raf_full.RAF
$'ufraw-batch raf_full.RAF' terminated by signal SIGSEGV (Address boundary error)

Here's the image I'm using: https://www.dropbox.com/s/qqriihvhtn8hf20/raf_full.RAF?dl=0

Can confirm that this is also an issue for the FUJIFILM GFX 50r.

@u/cgat

If you feel like building from source - I've attached a patch that I created to work with RAF files. There was a small bug.

There are some additional fixes to get it to compile on macOS. The main issue was line 36-37 of my patch.

By the way nice image in dropbox!!!
