            Bug ID: 25061
           Summary: git libxml++ test unit linking causes cre dump of the
                    /usr/bin/ld.bfd
           Product: binutils
           Version: 2.32
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: gold
          Assignee: ccoutant at gmail dot com
          Reporter: kloczko.tomasz at gmail dot com
                CC: ian at airs dot com
  Target Milestone: ---

Fedora rawhide.
libxml++ 3.0.1 + git patches with LTO causes sigsegv.
Tested that without LTO everything is fine.
