Here's how you can reproduce the breakage:


1) download 
https://drive.google.com/open?id=1yKav0llpfrLjuMZOCj6ZyfVWGbxZQzIA

(a binary module from a grub build)

2) run
objcopy --only-keep-debug ./ntldr.module ntldr.module.debug

to establish that objcopy is happy with the download

3) run

debugedit -l debug.source ./ntldr.module


4) run the same objcopy command again ---> kaboom

objcopy: ./ntldr.module: invalid relocation type 112
objcopy: ./ntldr.module(rel.debug_info): relocation 556 has invalid 
symbol index 7497472
objcopy: ./ntldr.module: invalid relocation type 98
objcopy: ./ntldr.module(rel.debug_info): relocation 557 has invalid 
symbol index 6648415
objcopy: ./ntldr.module: invalid relocation type 108
objcopy: ./ntldr.module(rel.debug_info): relocation 558 has invalid 
symbol index 7495522
objcopy: ./ntldr.module: invalid relocation type 117
objcopy: ./ntldr.module(rel.debug_info): relocation 559 has invalid 
symbol index 7499636
objcopy: ./ntldr.module: invalid relocation type 97
objcopy: ./ntldr.module(rel.debug_info): relocation 560 has invalid 
symbol index 25697
objcopy: ./ntldr.module: invalid relocation type 111
.....
Segmentation fault (core dumped)


Like Mark said, this isn't really the main issue for us; we would want 
to not have the binary file modified at all. Currently debugedit doesn't 
seem to provide that (and that's totally fine - a replacement is not 
difficult to find).
