See this DMG for example. https://github.com/kovidgoyal/calibre/releases/download/v4.4.0/calibre-4.4.0.dmg

[nix-shell:~/Downloads]$ undmg < calibre-4.4.0.dmg 
Segmentation fault: 11

[nix-shell:~/Downloads]$ file calibre-4.4.0.dmg 
calibre-4.4.0.dmg: bzip2 compressed data, block size = 100k

I suspect this is the same as #1 and #4.

This file (now available at https://download.calibre-ebook.com/4.4.0/calibre-4.4.0.dmg) appears to suffer the same issue as in #8 - extraction does not segfault when used as a parameter. There may still be an issue with a non-HFS file system.

$ undmg < calibre-4.4.0.dmg
error: only HFS file systems are supported.
fish: Job 1, 'undmg < calibre-4.4.0.dmg' terminated by signal SIGSEGV (Address boundary error)
