            Bug ID: 31106
           Summary: strip --strip-debug breaks relocations
           Product: binutils
           Version: 2.41
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: binutils
          Assignee: unassigned at sourceware dot org
          Reporter: stsp at users dot sourceforge.net
  Target Milestone: ---

Created attachment 15232

test case

Attached is a test-case.
It is an elf file fdppkrnl.35.10.elf
with debug info.

Please do:

```
$ readelf -r fdppkrnl.35.10.elf | grep ':s8:' | wc -l
65
$ strip --strip-debug fdppkrnl.35.10.elf
$ readelf -r fdppkrnl.35.10.elf | grep ':s8:' | wc -l
1
```

As we can see, strip removed relocations
to a particular symbol (1 reloc left from 65).
This renders the object disfunctional.

llvm-strip works properly and doesn't break
anything.
