Subject: dwz masks errors in writing output

Date: Sat, 19 Aug 2023 10:48:50 +0300

[Message part 1 (text/plain, inline)]

Package: dwz
Version: 0.15-1
Severity: minor

Dear Maintainer,

dwz(1) does not report actual errors in writing output binary.

For example,

$ gcc -g -x c - <<< 'int main(){return 0;}'
$ dwz -o /dev/full
dwz: a.out: elf_update failed

/dev/full is a special device that always produces ENOSPC on writing but dwz(1)
does not reveal the error unambiguously. I assume the tool should prints the
error messages as reported by the elf_errmsg() and the perror() functions.

And please forward this bug to upstream authors if appropriate. Their bug
tracker requires an account but registration is closed.
