            Bug ID: 68514
           Summary: [6 Regression] ICE in tr1/5_numerical_facilities
                    libstdc++ test cases
           Product: gcc
           Version: 6.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: rainer@emrich-ebersheim.de
  Target Milestone: ---

I get a lot of new failures for the tr1/5_numerical_facilities test cases of
the libstdc++ testsuite compared to a gcc trunk version dated 3 weeks back, see
https://gcc.gnu.org/ml/gcc-testresults/2015-11/msg00244.html and
https://gcc.gnu.org/ml/gcc-testresults/2015-11/msg02553.html

All like the following:

FAIL: tr1/5_numerical_facilities/random/minstd_rand.cc (test for excess errors)
Excess errors:
