            Bug ID: 94896
           Summary: [10 regression] ICE: canonical types differ for
                    identical types
           Product: gcc
           Version: 10.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
  Target Milestone: ---
            Target: sparc-sun-solaris2.11

Between 20200429 (27594524d8a93cddb197ad8c9d4075c5870f1473) and 20200430
(c416c52bcdb120db5e8c53a51bd78c4360daf79b), two tests regressed on
Solaris/SPARC:

+FAIL: g++.dg/cpp0x/alignas3.C  -std=c++14 (internal compiler error)
+FAIL: g++.dg/cpp0x/alignas3.C  -std=c++14 (test for excess errors)
