            Bug ID: 109589
           Summary: [14 regression] r14-35-g278f8f567b5470 breaks build
                    with older gcc build compilers
           Product: gcc
           Version: 14.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: seurer at gcc dot gnu.org
  Target Milestone: ---

g:278f8f567b5470e87e2e6482ee385d61c7f45a5d, r14-35-g278f8f567b5470

This update is causing build failures on a couple of our old RHEL 7.9 systems
if I use the system compiler.  If I use a newer build compiler it works fine.

gcc -v
gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) 


Is gcc 4.8.5 no longer suitable for builds?
