    • PR other/90695 reduce testcase to remove library dependency · 39d1184b
      This reproduces the original ICE fixed by r178857 (tested at r178852 and
      r178860), without depending on a libstdc++ header that keeps changing.
      
      The number of errors differs between C++14 and C++17 modes, so the fixed
      test uses dg-excess-errors to match any number of them. The precise
      errors aren't what's being tested for here anyway, the point of the test
      is to verify the ICE in PR 50391 is fixed.
