            Bug ID: 94223
           Summary: [10 Regression] -fcompare-debug -O0 failure on
                    cpp1z/init-statement6.C
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: zhroma at gcc dot gnu.org
  Target Milestone: ---

This commands:
gcc -c -O0 -std=3Dc++20 -fcompare-debug
gcc/testsuite/g++.dg/cpp1z/init-statement6.C
gcc -c -O0 -std=3Dc++2a -fcompare-debug
gcc/testsuite/g++.dg/cpp1z/init-statement6.C

fail on master (r10-7271) on ppc64le, work on 9.3 (only have -std=3Dc++2a) =
on
x86_64.

Running with -O1, -O2 or -std=3Dc++17 goes smoothly.=
