            Bug ID: 58702
           Summary: [4.9 Regression] ICE with undeclared variable in
                    OpenMP reduction clause
           Product: gcc
           Version: 4.9.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: reichelt at gcc dot gnu.org

The following invalid code snippet (compiled with "-fopenmp") triggers an ICE
on trunk:

=============================================
void foo()
{
  x;
#pragma omp parallel for reduction(+:x)
  for (int i = 0; i < 10; ++i) ;
}
=============================================

bug.cc: In function 'void foo()':
bug.cc:3:3: error: 'x' was not declared in this scope
   x;
   ^
bug.cc:4:40: internal compiler error: tree check: expected class 'type', have
'exceptional' (error_mark) in finish_omp_reduction_clause, at
cp/semantics.c:4966
 #pragma omp parallel for reduction(+:x)
