--- Comment #1 from Mark Wielaard <mark at klomp dot org> ---
Would you be able to give us a reproducer? And/or provide the 
I don't fully understand how you get at
cffc5784c4a469d09348e3f7ec53a74096fbd3.debug file? Are you using a standard eu
tool or something written by hand using the libdw and libelf libraries.

I think the issue is that something is providing unwritable to elf_memory and
that isn't expected. This might be a bug in elf_compress. And/or a design flaw
in elf_memory since you cannot provide a "mode".

Your fix fix might be correct. I have to think a bit more about it.
