           Summary: ICE: Segfault in gimple_build_call_1, at gimple.c:218
           Product: gcc
           Version: 7.0.1
            Status: UNCONFIRMED

  Target Milestone: ---

Version 6/7 (on x86_64 GNU/Linux) with option -fopenmp-simd
ICEs for testsuite files ./g++.dg/gomp/target-teams-1.C
and ./g++.dg/gomp/teams-1.C. Last one reduced :


$ cat z1.cc
void
bar ()
{
  #pragma omp target
  #pragma omp teams
    {
      int i;
      goto ok1;
      for (i = 0; i < 10; ++i)
        { ok1: break; }
    }
}


$ gcc-7-20170212 -fopenmp -c z1.cc
$ gcc-7-20170212 -fopenmp-simd -c z1.cc
z1.cc: In function 'void bar()':
