            Bug ID: 81004
           Summary: linking failed with -flto
           Product: gcc
           Version: 7.1.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: lto
          Assignee: unassigned at gcc dot gnu.org
          Reporter: a3at.mail at gmail dot com
                CC: marxin at gcc dot gnu.org
  Target Milestone: ---

After upgrading to gcc 7.1 -flto build failed during linking, I tried to reduce
amount of involved sources, but this is what I got:
  https://github.com/azat-archive/gcc7-lto-linking-issue

For this you need:
- cmake
- boost program_options (I tried with 1.64)
- gcc 7.1
- libstdc++

(And I added Dockerfile/docker-compose if you are using it).

Of course this is not the desired testcase, so if I can make it shorter, I will
get back to you,

Thanks!
