            Bug ID: 89110
           Summary: r268343 breaks several tests in c++2a
           Product: gcc
           Version: 9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: testsuite
          Assignee: unassigned at gcc dot gnu.org
          Reporter: mpolacek at gcc dot gnu.org
  Target Milestone: ---

Yet again I broke a few tests in C++20 mode :(

FAIL: g++.dg/other/nontype-1.C  -std=c++2a (test for excess errors)
FAIL: g++.dg/parse/crash13.C  -std=c++2a (test for excess errors)
FAIL: g++.dg/parse/error36.C  -std=c++2a (test for excess errors)
FAIL: g++.dg/template/error29.C  -std=c++2a (test for excess errors)

Fortunately, it's just a simple update of these tests; the compiler itself is
fine.
