            Bug ID: 82857
           Summary: libbacktrace: please support binaries stripped with
                    dwz -m (following the .gnu_debugaltlink)
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: doko at gcc dot gnu.org
  Target Milestone: ---

<doko> jakub: do you know if libbacktrace is working with dwz stripped debug
info?
<jakub> doko: no, somebody would need to write support for that (shouldn't be
very hard, I just don't have spare cycles for that right now)
<jakub> doko: pretty much one has to just write code to parse .gnu_debugaltlink
and find the other debug file, open it when it is needed
<jakub> doko: and handle the *_alt forms
<jakub> doko: to be precise, it works with dwz compressed debug info, but
doesn't with dwz -m
