            Bug ID: 66676
           Summary: pragma omp simd aligned(x) results in "internal
                    compiler error: Segmentation fault"
           Product: gcc
           Version: 5.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++

reproducer of bug

The Compiler segfaults if declaring a function with

  #pragma omp declare simd aligned(i_x)
   void ODEBenchmark_OpenMP_ver2(double *i_x){}

By specifying the alignment such as via
   #pragma omp declare simd aligned(i_x:128)
   void ODEBenchmark_OpenMP_ver2(double *i_x){}
compiles the program.

GCC version 5.1.0

Compile attached source code with
g++ -fopenmp ODEBenchmark.cpp
to reproduce bug.
